England centre Manu Tuilagi has apologised for playing a prank on British Prime Minister David Cameron during the British and Irish Lions' visit to Downing Street on Monday afternoon.
Tuilagi gave Cameron 'bunny ears' while stood behind and to the left of the Conservative Party leader as a group of players and management posed for a photo at the function to honour the Lions' 2-1 series victory over Australia.
Using Twitter to express his remorse for the incident, the Leicester Tigers later apologised.

@Manutuilagi
Apologies for messing around on Lions photo. No offence intended. 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 as he was fined £3,000 by the English 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 coach Martin Johnson.

Following his latest prank, Tuilagi's team-mates reacted on social networking site Twitter.
Ben Youngs, a fellow British and Irish Lion, England and Tigers player, tweeted: "The man@Manutuilagi just couldn't stop himself."
The scrum-half later removed the tweet and posted a picture of himself posing outside 10 Downing Street.

I think it's funny, I don't know why people are making such a big deal about it.
Have a sense of humour ...

That is a pretty epic photo

But I get why it can't be done, because professionals need to act professional in the public eye. They set examples. But I'm sure Cameron saw the funny side.
