Ed Miliband's plans to erode the voice of trade unions who helped elect him Labour leader will be voted on today at a special conference.

Delegates from constituency parties, socialist societies and trade unions will descend on east London's Excel conference centre to decide the future of their party, almost exactly 114 years after it was founded at a conference hosted by the Trades Union Congress.

And all but a handful of left-wing dissenters are expected to vote for the reforms proposed by former Labour general secretary Lord Collins.
