David Cameron today accused the BBC of peddling ‘b*******’ after claiming his favourite sport was foxhunting. The Tory leader hit back at presenter Andrew Marr, after being left baffled by questions during an interview on Sunday. It came as Mr Cameron turned the clock back to ape John Major’s election soapbox by climbing on to a wooden pallet to address the party faithful, but ended up being heckled by someone claiming ‘the NHS is dying’. David Cameron today turned the clock back to ape John Major’s election soapbox by climbing on to a wooden pallet to address the party faithful . Mr Cameron promised at the weekend that he would ‘take to the streets’ to defend the Tory record and urge voters to reject both Labour and Ukip. He said he had ‘upped the tempo’ to make the case that his economic plan is working. But he took time out from the campaign today to escalate his row with the BBC after appearing on the Andrew Marr Show on Sunday morning. Marr claimed the PM recently told the Countryside Alliance magazine that his favourite sport was fox hunting. ‘Is that really true?’ he asked. Mr Cameron replied: ‘No, I am a believer in…’ But Marr interrupted again: ‘You said it’s my favourite sport which I love.’ Again Mr Cameron insisted: ‘No I love walking, I love fishing, I love all sorts of sports.’ On the campaign trail in Yorkshire, Mr Cameron hit back at the BBC for claiming he had said foxhunting is his favourite sport . The Tory leader was heckled as he addressed party activists and workers from Decorative Panels during a campaign visit to Calder Valley . But in an article for the magazine, Mr Cameron actually said: ‘I have always been a strong supporter of country sports. ‘It is my firm belief that people should have the freedom to hunt, so I share the frustration that many people feel about the Hunting Act and the way it was brought in by the last government.’ Marr later admitted on Twitter that he had made an error: ‘Honest mistake – I was wrong – sorry. Cock up not conspiracy, but wrong on my part.’ Today Mr Cameron revealed how he thought it was wrong at the time of the interiview. He told the Spectator: ‘The old mental filing system, you’re going ‘drrrrrr’ through, and thinking… but I knew the article because I wrote it myself… I just thought maybe there’s something else. ‘You never know, something might have been written by someone else. So I thought it was bollocks. And it was bollocks.’ BBC presenter Andrew Marr has admitted he made a mistake on Sunday, but insisted it was a 'cock up not conspiracy' He insisted foxhunting was not his favourite sport, adding: ‘I am what I am. I’m a country boy, I like the countryside, I support country sports. ‘But my favourite sport is tennis, for the avoidance of doubt. And I’m quite good at it.’ Mr Cameron’s decision to use a soapbox came on the day Sir John urged the party to explain how economic growth improves people’s lives. But all did not go according to plan, as the Tory leader was was challenged by a heckler as he gave his stump speech at Decorative Panels in Calder Valley. The man, who appeared to be an employee of the firm, shouted: "The NHS is dying... Not talking about that, are you?" Colleagues seemed to urge him to be quiet, and the Prime Minister continued without further disruption. The man walked off back towards the offices immediately after the address without speaking to journalists.
