Nick Clegg reveals he was given a 'big green onesie' 10 January 2013 Last updated at 10:28 Deputy Prime Minister Nick Clegg has admitted he was given a "big green onesie" as a present - but that he has never worn it. The Lib Dem leader was appearing on his first weekly radio phone-in show on the London-based talk radio station LBC. He was asked the question by a caller from his constituency in Sheffield. Mr Clegg said the garment was still in its packaging but joked that if he was to ever wear it, it would be in the "privacy" of his home. This was the first of a series of weekly phone-ins, which will take place every Thursday on LBC 97.3 for half an hour. Difficult decisions One caller, a former Lib Dem councillor, told Mr Clegg he had torn up his membership card after nearly 40 years because he was "ashamed of the party." Fluent, honest and sincere. Not the verdict of one of Nick Clegg's spin doctors, but the LBC presenter James O'Brien who was on after the Deputy Prime Minister. Plenty of callers disagreed, but from Mr Clegg's perspective, the conversation has started. For some at least, a re-examination of his character is underway. And that is the point. Six callers, Claire, John, Lauren, Sara, Steve and Harry, politely gave him both barrels on everything from benefits, university tuition fee, trust and more. But no one was gratuitously rude and there were few questions he hadn't heard many times before. And yes, going into coalition was "monumentally controversial" Nick Clegg admitted. There is more to come. Mr Clegg will be back on the radio next week. "It was a good warm up session!" commented one caller afterwards. But Mr Clegg said he was "immensely proud" of the Liberal Democrats joining the coalition, insisting that the party had delivered on some key policies. He said he would not "paper over the difficult decisions" but maintained the party had had several victories in government, including more apprenticeships and more free childcare. The Liberal Democrat leader defended cuts to child benefit, under questioning from another caller, saying it had been a "difficult decision" but essential to cutting the deficit. He said means-testing the benefit would have been too bureaucratic and complicated. On tuition fees, Mr Clegg stopped short of saying it was one of his biggest political regrets, but said he regretted that it was a pre-election promise which the party could not deliver on. The deputy PM also revealed which Conservative Cabinet member he would most like to go for a drink with - Ken Clarke; although he declined to answer which Tory politician he most admired.
