News | PoliticsDavid Cameron rules out VAT rise after general election VAT rise ruled out: Prime Minister David CameronJoe Murphy @JoeMurphyLondon|Political Editor25 March 2015David Cameron wrongfooted Ed Miliband today by ruling out a rise in VAT after the general election.The pledge came as a surprise, because Chancellor George Osborne refused five times in a committee grilling yesterday to deny that he was secretly planning a hike.Mr Miliband challenged the Prime Minister to give a “straight answer” to the question of whether he would rule out a VAT rise.Mr Cameron responded in the last Prime Minister’s Questions before the election: “Straight questions deserve a straight answer: Yes.”Mr Miliband said: “Nobody is going to believe it.” The Tory leader retaliated by challenging Labour to rule out a National Insurance increase, something Mr Miliband declined to do three times.The exchange was watched from the Gallery by Mr Cameron’s wife, Samantha, and his children Nancy and Elwyn.Labour claimed that a VAT rise was the only option for the Conservatives to balance the nation’s books without borrowing or other tax rises.Treasury figures suggest a rise to 22.5% would cost a family with children an average of £450 a year and a pensioner couple £275 a year, according to Labour.
