First Test, Multan, day five: Pakistan 274 & 341 bt England 418 & 175 by 22 runs
Pakistan bowled England out for 175 after lunch on the final day to win the first Test in Multan by 22 runs.
Leg-spinner Danish Kaneria finished with 4-62, while Shoaib Akhtar took 3-49 and Mohammad Sami 2-31.
Andrew Strauss and Ian Bell added 40 to the overnight 24-1 but after they were caught off Kaneria the tourists folded.
Only Geraint Jones (33) provided any real resistance as the hosts took a 1-0 lead in the three-Test series, which continues in Faisalabad on Sunday.
It meant England's 44-year run without winning an opening Test in Pakistan goes on but, on a pitch that remained largely benign, it could have been so different.
Certainly, there was no indication of the mayhem to follow when Strauss and Bell confidently negotiated the opening 40 minutes.
Any early nerves were settled when Strauss produced a classic cover drive off the gentle medium pace of Shabbir Ahmed and Bell opened the face of the bat to guide Shoaib down to the third man boundary.
Bell had two slices of fortune when he edged one from Shoaib through where third slip would have been and saw his attempted cut off Kaneria pop wide and high of first slip.
His luck ran out when he cut one behind from the leg-spinner which was too close to his body, and four balls later Strauss pushed at one that was tossed up and succeeded only in edging to Hasan Raza at slip.
Collingwood, playing across the line to a full and quick delivery from Sami, was trapped in his crease and England had a mini crisis on their hands.
Sami was in full cry after Pietersen became his second victim
Pietersen and Flintoff chose bravado as their route out of the situation.
Pietersen played against the spin to launch Kaneria over mid-wicket for six and Flintoff, without any real footwork, drove Sami through the covers.
Neither were that convincing otherwise and it was no surprise when Flintoff's attempted sweep went straight down the throat of Younis Khan.
Another show of aggression cost Pietersen when he chased a wider one from Sami and was caught behind.
Pakistan were well and truly on top now and it needed something special from Jones and Giles to pull England out of the mire.
Giles had an escape when he got an edge to a Kaneria delivery and umpire Billy Bowden ruled in his favour.
But there was no doubt when the end came for him, a rapid yorker from Shoaib knocking out his middle and leg stumps.
Debutant Shaun Udal came to the crease at 117-7 and picked up two boundaries by paddle-sweeping Kaneria over mid-wicket and driving Shoaib down the ground.
The eighth-wicket pair maintained their defiance after the break and Jones played a handsome cover drive off Shabbir to illustrate that the runs were coming freely again.
They had put on 49 when a second and final collapse came.
Shoaib returned in place of Shabbir to bowl Jones and in the very next over Kaneria's googly found a way through Udal's bat and pad to the stumps.
Last man Steve Harmison chanced his arms and collected two boundaries off Shoaib but was deceived by a slower one to edge to first slip where Raza held on to cap a stunning fightback by the hosts.
Ultimately, England's batting - which had looked rusty in the warm-up matches - let them down and they have little time to work on it before the second game.
Pakistan's Salman Butt, who scored 196 runs in the Test, was named Man of the Match.
