England centre Manu Tuilagi has apologised for playing a prank on 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 centre said: "Apologies for messing around on Lions photo. No offence intended. Great Day at Downing Street. Thanks to Prime Minister for hosting us."
