1800: That's quite enough from me. Congratulations to Rangers on bagging the first silverware of the season. Thanks for your company and enjoy what's left of your weekend.
1755: I'll leave the final word to diska on Twitter #bbcsportsound: "What a great Old Firm final, good to see football being the main story this time. Smith got his tactics spot on."
1754: Apologies for the delay. My computer blew a gasket after 180 minutes of gut-bursting football at Hampden.
1737: The Rangers players start to pogo in celebration as red, white and blue tickertape falls from the main stand at Hampden. A hoarse Ally McCoist tells BBC Radio Scotland that it was a deserved victory for his side. "Now we can get on with the serious job of retaining the title," he croaks defiantly.
1735: A special cheer is reserved for Rangers manager Walter Smith as he is the last man to get his hands on the trophy.
1733: It seems a bit cruel to make 40-year-old Rangers captain David Weir climb the Hampden stairs but the big defender is smiling broadly as he lifts the League Cup aloft.
1732: The dejected Celtic players collect their runners-up medals and make a swift exit up the tunnel.
1730: Phew! That was some game. Not a great deal of silky football on display. It was all about blood, sweat and snotters on a terrible Hampden pitch. Rangers wanted it just that bit more and ran out deserved winners. Too many Celtic players had an off day.
1727: Full-time: Celtic 1-2 Rangers It's a 20th trophy for Rangers manager Walter Smith, in his final season at Ibrox. Steven Davis and Joe Ledley exchanged first-half goals and Nikica Jelavic grabbed the all-important extra-time winner.
1725: Celtic are down to 10 men in the final few seconds as Emilio Izaguirre sees red for a cynical block on Vladimir Weiss. Celtic keeper Fraser Forster was miles out of his goal, making it a scoring opportunity.
1724: The ball ricochets around the Rangers penalty box before falling for Gary Hooper but Steven Whittaker throws himself in front of the Celtic striker to make a vital block.
1722: And that'll be a yellow card for Mr Diouf for taking a ludicrous tumble. An absurd dive.
1721: Diouf immediately slips a fantastic pass to Vladimir Weiss but Fraser Forster gets down quickly to make the block and save a certain goal.
1720: El Hadji Diouf is getting a late taste of the action, replacing the scorer of Rangers' second goal, Nikica Jelavic. Cue a chorus of boos from the Celtic fans.
1717: The pressure on the Rangers defence is eased as Ki shoots wastefully over the crossbar from long range.
1715: The ball is rolled to Sasa Papac but the Rangers defender's strike thunders back off the defensive wall.
1714: It's another footrace between Nikica Jelavic and Charlie Mulgrew and the Celtic defender is booked for hauling the striker down at the edge of the penalty box.
1713: "Celtic are going to have to find a bit of zip from somewhere if they're going to get back into this match." BBC Scotland TV pundit Billy Dodds.
1711: Vladimir Weiss is geeing up the Rangers crowd as the ball goes out for a throw-in. The fans in blue are certainly making the most noise at a febrile Hampden.
1710: From swizzo_owen on Twitter #BBCSportsound: "Rangers have scored both their goals in-off the same post. What's the odds on that?"
1708: That's the end of the first half of extra-time. Advantage Rangers. Paddy McCourt has got some cheek grabbing a quick drink. he's only been on for a matter of minutes!
1707: Rangers are sitting very deep, with goalscorer Nikica Jelavic playing like a third centre-half at the moment.
1705: Paddy McCourt is on for Celtic. Kris Commons is the man to make way.
1700: Vladimir Weiss takes a quick free kick and Nikica Jelavic outraces Charlie Mulgrew and slips a shot beyond the advancing Fraser Forster. The ball strikes the post and bounces maybe a foot out before spinning across goal and inside at the other post.
GOAL! Celtic 1-2 Rangers (Jelavic)
1658: Mark Wilson is booked for cynical clip on the heels of Vladimir Weiss. Nikica Jelavic's free kick is deflected off a head in the defensive wall and Fraser Forster makes a great save to claw the ball away. The keeper was able to throw up a hand and scoop it over the crossbar after going the wrong way.
1657: Georgios Samaras does well to gallop down the left and deliver a really good cross but none of his team-mates can keep up and Rangers clear without too much fuss.
1655: From mwdickson on Twitter #BBCSportsound: "Weiss' pace and trickery is exactly what Rangers need! Celtic looking the stronger at the end. Extra time = extra controversy!"
1654: We're off again. Will we get a winner in extra time or are we heading for nerve-shredding a penalty shoot-out?
1652: Rangers manager Walter Smith has taken his weary troops aside for a quick briefing, while celtic's Neil Lennon, serving a touchline ban, barks his instructions into a wee microphone in his jacket - very James Bond.
1649: Do you want some more? Well, you're getting it. There will be half an hour of extra time, with a fascinating game locked at 1-1.
1647: Rangers throw on tricky winger Vladimir Weiss for the exhausted Kyle Lafferty. The gangly Northern Ireland forward has run himself into the ground.
1646: Rangers are on the ropes as Celtic probe for an opening and a killer late goal.
1645: 90 minutes are up. We'll get three more minutes of injury time at Hampden.
1644: From ghspence on Twitter #BBCSportsound: "Hooper having a mare! Be just like him to sneak the winner though?"
1643: The TV sound is back just in time to hear commentator Liam McLeod describe a routine catch for Neil Alexander from a Ki Sung-Yeung free kick
1640: The ball drops for Joe Ledley at a Celtic corner but the Welshman's shot lacks power and Neil Alexander gets down smartly to make the save. Still 1-1. Are we heading for extra time?
1639: "It's like treading through treacle on that pitch. There are a lot of tired legs down there." BBC Radio Scotland commentator David Begg is still going strong, although there appears to be a problem with the TV commentary.
1637: Madjid Bougherra trudges off. The Rangers defender must be injured. Kyle Hutton is his replacement and goes into midfield. Steven Whittaker slips into central defence beside skipper David Weir and Maurice Edu takes over at right-back.
1635: From LeBonDon on Twitter #BBCSportsound: "What's happened to Celtic this second half? We looked far better in the first. Get intae them!!!"
1633: Kris Commons can't quite believe it as he is punished for handball. The Scotland international may have been trying to catch the eye of rugby coach Andy Robinson as he tried to gather a long, high ball after getting a substantial nudge in the back from Madjid Bougherra.
1631: Still 1-1 at Hampden. Celtic striker Gary Hooper have been starved of decent service all afternoon but he gets a sniff at the edge of the penalty box, only to shot too high.
1629: From dj_jenns on Twitter #BBCSportsound: "Rangers have been dominating this match so far, I can see things kicking off in the final 20 minutes."
1626: Celtic are awarded a free kick 25 yards out but Kris Commons sends a squiggling strike horribly wide. Neil Lennon's side really haven't got going in this second half. Glenn Loovens is getting ready to replace Thomas Rogne. The young Norwegian has looked a little shaky at the back.
1623: It's all Rangers at the moment. Blue shirts are streaming forward at every opportunity. Gregg Wylde gets himself into a promising position but mis-fires wildly with his shot from the edge of the penalty area.
1620: Celtic midfielder Beram Kayal picks up a yellow card for a late, sliding tackle on Steven Nasimsith. Gregg Wylde fires in the free kick from 25 yards and Fraser Forster has to claw the ball away as it heads for the junction of post and crossbar.
1618: Scott Brown's miraculous recovery lasts all of a minute. He's off, with Ki Sung-Yeung on in his place.
1617: Celtic skipper Scott Brown is in trouble. He pulled up during a footrace and then sat down waiting for medical attention. A quick rub with the magic sponge and he's back on his feet, frisky as a spring lamb.
1615: Another penalty shout! This time it's Maurice Edu flicking the ball up onto the arm of Mark Wilson. Joe Ledley hammers the ball to safety as referee Craig Thomson ignores the Rangers appeals.
1611: If anything, the pace has increased from a mere whirlwind to a blur! Both sets of players are snapping and snarling into every challenge but it's not been a dirty game at all.
1607: Following a Rangers corner, the ball drops to Nikica Jelavic but the striker blazes his rushed first-time volley from eight yards way over the crossbar.
1605: A let-off for Rangers defender Sasa Papac as he makes a mess of clearing a low cross from Kris Commons and the ball bobbles a few inches wide of his own goal.
1601: Great start from Rangers as Kyle Lafferty is inches away from connecting with a flashing cross from Gregg Wylde and Celtic keeper Fraser Forster beats away a thumping shot from Steven Whittaker.
1600: We're off again. No changes in personnel.
1557: We haven't seen much composure on the ball but I'm not complaining. The game has been played a cracking pace and there has been no shortage of incident. Can the teams it up after the interval?
1555: From danhitmanhearn on Twitter #BBCSportsound: "Im a Chelsea fan and I'm tempted not to bother watching the Man City game if this match carries on as it is!" Stay with us Dan. You know it makes sense.
1552: We're getting multiple replays of the penalty incident. Celtic defender Thomas Rogne was daft to waft a leg out but he merely tickled the sock of Nikica Jelavic. Definitely not a penalty. Well done the match officials.
1548: "What a game. Today's it's been really exciting. The play has raged from one end back to the other." Scotland coach Craig Levein is enjoying himself at Hampden.
1545: Half-time: Celtic 1-1 Rangers Well, it's all square after a breathless first 45 minutes. Steven Davis and Joe Ledley grabbed the goals but the big talking point is the penalty U-turn from referee Craig Thomson.
1542: The game is going through a rather scrappy phase, with neither midfield able to get a grip on proceedings. It's 1-1 with just a few minutes to go until half time.
1539: From andy_purcell on Twitter #bbcsportsound: "Great example of teamwork between the officials to keep the cup final on track." Yup, it looks like Craig Thomson took advice from one of his assistants on his penalty U-turn.
1537: Kris Commons, who is no slouch from long-range, has a dig but it's not one of his best efforts and Rangers keeper Neil Alexander gathers comfortably.
1536: Fraser Forster gets a huge cheer from the Celtic fans as he races from his line to pluck a Madjid Bougherra cross out of the air, barging a couple of Rangers players out of the way as he does.
1532: Extraordinary! Referee Craig Thomson points to the penalty spot as Nikica Jelavic tumbles over the leg of Thomas Rogne. But wait a minute, he's gone and changed his mind and now he's booking the Rangers striker for simulation. A huge call from the whistler and TV replays appear to back the man in black.
It's the Celtic fans making all the noise now as Georgios Samaras flicks on a cross from Emilio Izaguirre and Joe Ledley heads home from six yards.
1529: GOAL! Celtic 1-1 Rangers (Ledley)
Rangers are ahead at Hampden as Steven Davis drives at the Celtic defence and lets fly with a shot from 20 yards. The Rangers man didn't exactly catch it properly but it crept past the outstretched Fraser Forster and bounced in off the post.
1523: GOAL! Rangers 1-0 Celtic (Davis)
1521: Best chance of the game! Celtic skipper Scott Brown dives in to connect with a Kris Commons cross from the left but steers his low header narrowly wide of the post.
1518: Neither goalkeeper has been tested as the play rages on at a furious pace. Still 0-0 at Hampden Park.
1515: Two shouts of "penalty" from the Celtic fans as Gary Hooper collapses on the edge of the box and Mark Wilson takes a tumble a second later. Referee Craig Thomson simply shakes his head.
1512: "Rangers are on top. Georgios Samaras looks like the only Celtic player who has really settled out there," says BBC Radio Scotland pundit Murdo MacLeod.
1510: From euanblack on Twitter #bbcsportsound: "The pitch looks terrible, as a Celtic fan I can't help but worry that it will suit Rangers style of play more than ours!"
1508: Kyle Lafferty gets a second bite after his header is blocked and his follow-up shot cannons off Celtic defender Charlie Mulgrew and out for a corner that comes to nothing.
1507: It's been a typically frantic opening and the rutted pitch is not helping as the ball bobbles around like the classic 'hot potato', your school coach always banged on about./CPS:EVENT>
1505: Rangers striker Nikica Jelavic pops up at the back post but fails to connect properly with a first-time effort, making life simple for Celtic keeper Fraser Forster.
1502: Celtic forward Georgios Samaras breaks down from left flank and rampages at the heart of a Rangers defence before the ball is hacked clear. The big Greek is a bit hit and miss but he loves these Old Firm games.
1501: "It's tough to call. Rangers are sort of having a go today. We know what Celtic are going to do. It's certainly going to be an interesting contest." BBC Scotland pundit Billy Dodds at Hampden.
1500: Referee Craig Thomson sounds his whistle and Celtic kick off. Hold on to your hats...
1456: The teams march on to the Hampden turf, which is looking pretty ropey, and the crowd erupts into a cacophonous din.
1455: "This could be a changing of the powerbase in Glasgow to Celtic. If they can win this one today, it's hard to see them being stopped for the rest of the season." BBC Scotland pundit Pat Nevin at Hampden.
1452: "Rangers have a height advantage for the first time in a while today. It will be interesting to see how set-pieces go." Scotland coach Craig Levein.
1450: From Colin on the BBC Sportsound Facebook page: " 'All you need is love' booming from the Hampden sound system. I don't think that will work!"
1447: From thefootygaffa on Twitter #bbcsportsound: "If Celtic can play a high tempo game, fatigue may be an issue for the Rangers players in their third game of the week."
1445: Rangers assistant manager Ally McCoist is the last player to score a hat-trick in an Old Firm match, having netted all of Rangers' goals in their 3-2 final win over Celtic in 1984.
1444: Will we get a few goals today? The 1974/75 final yielded a record nine as Celtic beat Hibs 6-3. Poor Joe Harper scored a hat-trick at Hampden and ended up on the losing side.
1441: From Luke in Plymouth by text on 80295: "As a Rangers fan I'm glad to see four at the back for a Cup final. Was getting on my nerves when we kept playing five when we needed to attack. I'm optimistic now!"
1438: Celtic have the edge in this season's Old Firm encounters, with three wins from the five previous matches. Rangers won the first game and we had a draw in the Scottish Cup before Celtic prevailed in a stormy replay.
1434: Rangers will be hoping Kyle Lafferty and Steven Whittaker can cope with the marauding runs of Celtic left-back Emilio Izaguirre. The Honduran is a real speed merchant and loves to get forward. A definite candidate for Scotland's player of the year.
1430: BBC One Scotland have got a couple of heavyweight guests for this afternoon's big game. Scotland manager Craig Levein and Everton boss David Moyes join the busiest pundit in showbiz, Pat Nevin, and host Rob MacLean in the studio. Refresh this page to see the programme right here.
1428: From Bryan by text on 80295: "Looking at the Celtic defence, Rangers can do some damage... If they actually have a go! Jelavic it's your chance."
1426: Celtic boss Neil Lennon is serving a touchline suspension but he can address his players in the dressing room before the game and at half time, contrary to some reports.
1423: Rangers assistant manager Ally McCoist holds the record for the most winners' medals for a player in the League Cup - he picked up nine between 1983 and 1996.
Former Rangers midfielder Kevin Thomson has popped up on Twitter:
"Good luck 2 the Gers 2day loved playing in cup finals special days for any player never mind an old firm final." Thomson was one of two Rangers players sent off in last year's final. Despite being reduced to nine men they beat St Mirren thanks to a late goal from Kenny Miller.
1415:From fuzzyfozza on Twitter #bbcsportsound: "Really pleased Rogne plays ahead of Loovens. I feared the big Dutchman would cost us the game."
1414: "It's not about formations. It's all about individuals on the day and who wants it most." BBC Radio Scotland pundit Murdo MacLeod.
1410: What kind of cup final day do you call this? It's cold and wet in Glasgow. It could be worse. Hibs and Kilmarnock were playing in a snowstorm during the 2007 final!
1408: Rangers manager Walter Smith is chasing his 20th trophy for the club, having won the League Cup five times before. Of course, Celtic's Neil Lennon is after his first silverware as a gaffer.
1405: As expected, Celtic duo Scott Brown and Mark Wilson return from suspension, with Efrain Juarez and Ki Sung-Yeung dropping out from the team that beat Inverness in the Scottish Cup on Wednesday.
1402: Early team news: Celtic chose Thomas Rogne in central defence, while Rangers give teenager Gregg Wylde a start in midfield and Kyle Lafferty is fit.
1359: Rangers have won the League Cup 26 times, while Celtic have been successful on 14 occasions. This is the 13th Old Firm final, Rangers having enjoyed eight victories.
1355: Good afternoon and welcome to our coverage of the Co-operative Insurance Cup final. It's the sixth instalment of this season's Old Firm saga and when I say we've got it covered, I mean it. You can watch the game on this very website since we'll be streaming BBC One Scotland's output from 1430. You can also listen online to BBC Radio Scotland's commentary from Hampden. I'm afraid all of the fun is available to UK users only. Those of you overseas will have to make do with my text updates.
