Sir Chris Hoy has been named as Great Britain's flagbearer for the opening ceremony of London 2012 on Friday, the British Olympic Association has confirmed.
It is the second successive time the cyclist has been given the honour - he also carried the Union Jack in the closing ceremony at Beijing in 2008.
He is also the first cyclist to have been nominated to carry the Union Flag at an Opening Ceremony.
The Scot, a gold medal winner at the two previous Games, won the biggest number of votes among the 542 members of the British team.
Sir Chris said: "I'm absolutely delighted and honoured to have been voted as the flag bearer for Team GB. To lead out your team at a home Olympics is truly a once in a lifetime opportunity and one that that I can't wait to experience in just a few days time."
Others who also received support included Alison Williamson, the archer who will be competing at her sixth Olympic Games.
A number of other possible candidates such as sailor Ben Ainslie and swimmer Rebecca Adlington were not on the short-list because their competition schedule means they are not able to attend the opening ceremony.
Meanwhile, London 2012 chairman Sebastian Coe insists the choice of the person to light the Olympic Flame on Friday is not his call.
Coe says he has an input but that the final decision will be taken by the opening ceremony creative teams headed by Danny Boyle and Stephen Daldry.
That appears slightly at odds with British Olympic Association chief executive Andy Hunt, who on Saturday stated that it would be a joint decision between the BOA and London 2012.
Coe also insisted that despite a report last week he is not pushing the claims of his best friend Daley Thompson over Sir Steve Redgrave.
"It will be a judgement made by our creative teams led by Danny Boyle and Stephen Daldry, and of course I will be a part of that but I have been very, very clear that it is not my call," Coe said.
He added: "I am certainly not pushing one person over another, and it still has not been decided, absolutely not."
The identity of the person is supposed to be kept a secret until the actual moment of the flame-lighting.
Other possible people for the lighting include Dame Kelly Holmes, Roger Bannister or even David Beckham. The creative teams have even discussed whether the person needs to be well-known or should be symbolic - for example a child from the East End of London.
Coe added: "Do I have a view on this personally or privately? Yes of course.
"Have I asked our creative teams to get their minds around this? Yes I have. Have we made a judgement about this? No, we haven't.
"Is Daley Thompson a really close friend of mine? Yes he is, it's probably not the best-kept secret that he's probably my closest friend, and do I get on well with Steve Redgrave? Yes I do.
"This is not that complicated nor conspiratorial. This isn't an exact science. I have said all along it may be very obvious - but it may not be."
