Manu Tuilagi sorry for prank on PM David Cameron

England centre Manu Tuilagi has apologised for playing a prank on Prime Minister David Cameron during a visit to Downing Street on Monday.

Tuilagi made a 'bunny' gesture with two fingers behind the Conservative Party leader's head while posing for a photo with British and Irish Lions players.

The squad were attending a function to honour their series win in Australia.

"Apologies for messing around on Lions photo. No offence intended," Tuilagi tweeted  later on Monday.

"Great Day at Downing Street. Thanks to Prime Minister for hosting us."

It is not the first time Tuilagi has been the centre of controversy.

He was fined £3,000 by the Rugby Football Union after he jumped from a ferry during England's World Cup campaign in New Zealand two years ago.

Tuilagi was cautioned by police on that occasion and disciplined by then England manager Martin Johnson.

Following his latest prank, Tuilagi's Leicester, England and Lions team-mate Ben Youngs, tweeted: "The man just couldn't stop himself."

The scrum-half later removed the tweet and posted a picture of himself posing outside 10 Downing Street.

Gloucester fly-half Freddie Burns, an England team-mate, tweeted: "Great bottle from Manu Tuilagi! Haha."
