Ed Miliband's plans to reform the union-Labour link have been embraced by Tony Blair, who described them as a "bold and strong" move.
Speaking on Sky News, the former prime minister said: "I think this is a defining moment. It's bold and it's strong. It's real leadership, this. I think it's important not only in its own terms, because he's carrying through a process of reform in the Labour party that is long overdue and, frankly, probably I should have done it when I was leader.
As union leaders lined up to criticise Miliband for embracing "dog whistle politics" that were not the concern of the ordinary voter, Blair said it was a real act of leadership.
"What he's doing, and I think this is also very important for the country, is that he's sending a very strong message to the country that in the end he will do what's right, he'll govern for all the country and not simply for one section of it. This is big stuff and it takes a real act of leadership to do it."
