Lord Mandelson: Labour's 'terrible mistake'
Lord Mandelson has said that Ed Miliband, who stepped down from the Labour leadership on Friday, threw away the party's chance of returning to power by shifting it to the left.
The peer, who was closely involved in former prime minister Tony Blair's election victories, also said Labour had lacked an economic plan.
His comments came as senior figures in the party spoke of its future direction.
