England rugby union centre Manu Tuilagi has apologised for playing a prank on British Prime Minister David Cameron during the British and Irish Lions’ recent visit to Downing Street.

Tuilagi gave Cameron “bunny ears” while standing behind and to the left of the Conservative Party leader as a group of players and management posed for a photo at the function on Monday to honour the Lions’ 2-1 series victory over Australia this year.

The Leicester Tigers centre took to Twitter to express his remorse for the incident.

“Apologies for messing around on Lions photo,” he tweeted.

“No offence intended. Great Day at Downing Street. Thanks to Prime Minister for hosting us.”
