LONDON (AP) — The biggest delegation at the London Olympics will be in red, white and blue.

The Union Jack variety, though.

The United States will have only the second-biggest squad in London, with 530 competitors, while the British will have 542 athletes.

The hosts are fielding competitors in all 26 sports as the Olympics return to the British capital for the third time.

Britain's chef de mission Andy Hunt says "to have the largest delegation of all 204 competing nations at the London 2012 Olympic Games is a fantastic achievement."

Russia will have the third-largest delegation followed by China.
