England football manager Sven-Goran Eriksson will join London's bid team for the 2012 Olympics vote in Singapore next week.
Football: Sven-Goran Eriksson, Sir Bobby Charlton, David Beckham
Athletics: Jonathan Edwards, Cathy Freeman, Dalton Grant, David Hemery, Colin Jackson, Denise Lewis, Daley Thompson
Rowing: Sir Steve Redgrave, Sir Matthew Pinsent
Sailing: Shirley Robertson
Paralympics: Ade Adepitan, Dame Tanni Grey-Thompson
The Swede was a surprise name on a list of ambassadors, which includes the national team captain David Beckham.
Eriksson is in the news over his affair with PA Faria Alam, who is claiming unfair dismissal from the Football Association at an employment tribunal.
Other delegates include Olympic greats Daley Thompson and Sir Steve Redgrave.
London will be up against four other cities - Madrid, Moscow, New York and Paris - at the International Olympic Committee vote on Wednesday 6 July.
In addition to Beckham and Eriksson, England World Cup winner Sir Bobby Charlton will be another footballing ambassador.
Despite none of the trio having competed at an Olympic Games, bid leader Lord Coe believes they will add to the city's campaign.
Of Eriksson, Coe said: "He is the national manager of our national game.
All three main political parties will be represented in Singapore
Prime Minister Tony Blair (Labour)
Culture Secretary Tessa Jowell (Lab)
Sports minister Richard Caborn (Lab)
Shadow sports minister Hugh Robertson (Con)
Liberal Democrat spokesman Don Foster
"The fact that he's endorsing this bid, having worked in a number of other cities and having chosen to make this his home, I think is part of the narrative of this city."
Beckham was born in the east end of London, which would house a massive Olympic park if Coe's team succeeds with its bid.
"He's a boy from the east end, which is very much part of the regeneration story," said Coe.
Without a unified team, Britain does not compete at present in the football championships at the Olympics but Coe suggested that could change if the Games are held on home soil in 2012.
The bid team will be bolstered by the presence of Prime Minister Tony Blair, who is set to make a flying visit to Singapore before returning for the G8 summit in Gleneagles, which starts on the same day as the vote.
His wife Cherie, who is also a London 2012 ambassador, will be in Singapore, as will representatives of the three main political parties.
