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 .
