Cameron's profane joke at expense of 'idle' Clegg A spokesman for Mr Clegg said last night that the message from Mr Cameron was not passed on. "Nobody has approached Nick in a restaurant to pass on a message from the prime minister - and I've heard that from the horse's mouth," the spokesman said. He added: "Sometimes he is allowed to have dinner with his wife after working hard throughout the day." The Prime Minister has himself been criticised for his love of relaxation. A biography of the Prime Minister last year quoted a close ally as saying: "If there was an Olympic gold medal for 'chillaxing," he would win it." Mr Cameron is also said to enjoy playing games such as "Fruit Ninja" on his iPad. The Prime Minister has always insisted that he works "incredibly hard" and earlier this year disclosed that he often works in his pyjamas because he gets up so early. His use of a profanity to describe his Coalition colleague comes after he was reported this week to have called environmental levies on energy bills "green crap." The Prime Minister has regularly mocked Mr Clegg since the pair began sharing power in 2010. He is thought to hone his tennis skills at weekends using a tennis machine he refers to as "the Clegger." In 2011 it was disclosed that Mr Clegg's office sent out a memo to other Whitehall departments telling them that routine reports and memos would not be put into the Deputy Prime Minister's "red box" after 3pm between Monday and Thursday. Opponents accused Mr Clegg of "putting his feet up" - a claim vigorously denied by the Deputy Prime Minister's office.
