Ed Miliband attacks Unite leader Len McCluskey's comments 24 April 2013 Last updated at 21:21 Ed Miliband has called the leader of Labour's biggest donor union "reprehensible," accusing him of seeking to "divide" the party. Len McCluskey, general secretary of the Unite union, said Labour would be "cast into the dustbin of history" if it was "seduced" by supporters of Tony Blair. Mr McCluskey did "not speak for the party," said Mr Miliband's spokesman, The Labour leader was elected with union backing, but Mr McCluskey criticised several members of his team. He told the New Statesman magazine that listening to figures such as shadow foreign secretary Douglas Alexander, shadow defence secretary Jim Murphy and shadow work and pensions secretary Liam Byrne, could lead to defeat, and urged Mr Miliband to go into the 2015 general election with "a team that he's confident in." Regrettable He said: "Ed Miliband must spend most of his waking hours grappling with what lies before him. If he is brave enough to go for something radical, he'll be the next prime minister. If he gets seduced by the Jim Murphys and the Douglas Alexanders, then the truth is that he'll be defeated and he'll be cast into the dustbin of history. He added: "Liam Byrne certainly doesn't reflect the views of my members and of our union's policy, I think some of the terminology that he uses is regrettable and I think it will damage Labour. Ed's got to figure out what his team will be. Mr McCluskey also said: "We believe that Ed should try to create a radical alternative. My personal fear, and that of my union, is that if he goes to the electorate with an austerity-lite programme, then he will get defeated. But a spokesman for Mr Miliband said: "Len McCluskey does not speak for the Labour Party. This attempt to divide the Labour Party is reprehensible. It is the kind of politics that lost Labour many elections in the 1980s. It won't work. It is wrong. It is disloyal to the party he claims to represent. Mr Murphy took to Twitter to criticise the union leader, saying: "It's disappointing in advance of important local elections that Len McCluskey turns his fire on Labour."
