Britain's Prime Minister David Cameron plays tennis with London mayor Boris Johnson in Trafalgar Square in London, on Thursday, Sept. 8.

It may appear that Britain's Prime Minister David Cameron has a hard time resisting tennis in any form while wearing a token white shirt and blue tie.

Today, Cameron picked up a racquet and faced off against London Mayor Boris Johnson in support of Paralympic International Day in Trafalgar Square.

The prime minister donned a similar look during President Obama's visit, and the subsequent duo playing table tennis.
