Luke Bozier, Labour's former e-campaigns manager, told The Independent that Labour is no longer a "party of aspiration"; David Cameron is continuing Tony Blair's education and welfare reforms; Mr Miliband is proving a "disaster" as Labour leader; his party had "zero credibility" on the economy.
He declared: "Labour has a vacuum of policy and a vacuum of vision. Even if Ed Miliband had a policy and a vision, he is clearly unable to communicate it or connect with he electorate in any meaningful way."
