The Prime Minister has launched a scathing attack on the Conservatives over cuts to public spending. At the GMB's annual conference in Blackpool, Gordon Brown accused the Tories of planning to take money from public services to fund inheritance tax cuts. He said: "We have a duty to say we must fight as we have never fought before for our public services. "We must expose the damage that will be caused by cutting public services to fund inheritance tax. These are the wrong priorities and we will expose them." The speech to 500 delegates comes a day after Shadow Chancellor George Osborne demanded Labour come clean about the scale of spending cuts in the next parliament - no matter who wins the General Election. He said: "The real dividing line is not cuts versus investment, but honesty versus dishonesty." He added: "We should have the confidence to tell the public the truth that Britain faces a debt crisis; that existing plans show that real spending will have to be cut, whoever is elected; and that the bills of rising unemployment and the huge interest costs of a soaring national debt mean that many government departments will face budget cuts."
