London faces Paris for the right to stage the Games in a tight race which also includes Madrid, Moscow [Images] and New York.

Beckham, dressed in a pin-striped suit and gold tie, stopped just briefly to sign autographs for two children waiting outside the British High Commissioner's house to catch a glimpse of him before he headed inside for a reception.

"It felt really good to see him live, and not just on TV," said 12-year-old Tim Supramaniam, who waited for Beckham nearly two hours with his brother, both of them donning red England [Images] football shirts.

Double Olympic medallist Sebastian Coe, who is at the head of the London bid team, arrived just minutes after Beckham and told reporters: "London is the only bid. We are very happy and privileged to be represented here."

The International Olympics [Images] Committee will vote on Wednesday on who will stage the Summer Games.
