The nation's favourite DJ Terry Wogan has been awarded an honorary knighthood in the Queen's Birthday Honours list.
Wogan's wry, relaxed presenting style is hugely popular
The radio and TV presenter joins a select group including Bob Geldof and Microsoft founder Bill Gates in receiving the honour, usually given only to British and Commonwealth citizens.
It is recognition of the contribution to broadcasting of the genial Irishman, who attracts an audience of more than 8m people to his weekday morning BBC Radio 2 breakfast show Wake Up To Wogan.
His presenting of the annual Children in Need BBC charity fundraising event and the Eurovision Song Contest, among numerous other credits, has made him a national institution.
When once asked about the secret of his success, he quipped: "I put it all down to clean living and plenty of roughage."
Born in Limerick in 1938, Wogan went into banking after college before switching careers after five years to join Ireland's national Radio Eireann as a newsreader and announcer.
He moved into light entertainment as a disc jockey and host of Irish TV quiz and variety shows before joining BBC radio to host Midday Spin.
Wogan was among the first DJs on Radio 1 when the station started in 1967 and took on an additional show on Radio 2 in 1969.
The golf mad father of three took over the morning show on Radio 2 in April 1972.
He went on to win a string of awards including the Variety Club Award for Radio Personality Of The Year in 1974.
Wogan hosts the annual Children In Need appeal
Wogan left the station in 1982 to host Wogan, his own early evening BBC1 chat show three times a week.
He interviewed everyone from the Royals to the Hollywood A-list, with a drunken George Best providing one of many memorable moments.
He was voted TV personality of the year 10 times by TV Times magazine readers.
After 10 years, the show finished and Wogan returned to Radio 2 to host Wake Up To Wogan.
The show features his own wry take on the world and the often surreal input of his audience, who he dubbed TOGs, or Terry's Old Geezers or Gals.
Their enthusiasm has spread to a host of fan memorabilia including sweatshirts with the legend: "Do I come here often?"
Wogan's contribution has been one of the key factors in the rise of Radio 2, once considered an unfashionable station for only older listeners.
He has won numerous awards including the 1994 Sony award for best breakfast show.
He was recently named Radio Broadcaster of the Year at the Broadcasting Press Guild awards
Wogan was one of the founders of Children in Need and has hosted the telethon
for the past 20 years, helping to raise more than £400 million for charity.
His wry commentary on the Eurovision Song Contest, particularly during the voting, is the only reason some UK viewers tune in to the annual event.
Wogan has notched up 38 years of BBC service
A typically sarcastic comment came in 1998: "Twelve points from Slovakia to Malta really restores your faith in the chaos theory, doesn't it?"
He has hosted Lunchtime With Wogan, Come Dancing, Celebrity Squares, New Faces and Blankety Blank.
Other presenting roles include Wogan's Island, Do The Right Thing, Auntie's Bloomers, Auntie's Sporting Bloomers and the National Lottery Live.
Wogan's honorary knighthood follows the honorary OBE he received in the 1997 New Year Honours List.
