One criticism made of Ed Miliband's recent speech on the Labour-union link was that he failed to provide enough detail on how and when the proposed changes, most notably the introduction of an opt-in system for affiliated members (which will cost Labour millions  in funding), would be introduced. Would the reforms be in place before the next election?
It's a point the Labour leader will seek to address at an event in Coin Street, London, tonight with voters, trade unionists and party members. In remarks before the Q&A, Miliband will announce that at the next meeting of Labour's NEC he will ask members to agree that a Special Conference should be held next spring to approve the changes. It's an echo of the approach previously adopted by Tony Blair, who similarly held a Special Conference in Easter 1995 to approve his revision of Clause IV, and means that the Labour leader won't have to wait until the 2014 conference to seek formal endorsement of the reforms. The announcement should go some way to appeasing those who have criticised the lack of consultation with party members. Following Miliband's speech, Compass head Neal Lawson wrote : "Once Labour would have called a special conference; now everyone just waits for the leader's speech." The Labour leader has just confounded the sceptics.
Miliband will also outline what the party describes as a "route-map to the Special Conference". As previously announced, former party general secretary and TGWU official Ray Collins will lead a review into how the reforms will be implemented and the wider implications for candidate selections, annual conference, the National Policy Forum and the leadership election system. At present, the party leader is chosen by an electoral college split three ways between the party's 272 MPs and MEPs, all party members (193,000 at the last count) and members of affiliated  trade unions and socialist societies (around 2.7 million). But should Miliband make all trade unionists who choose to donate full members of the party (as seems likely), the third of these sections would effectively cease to exist.
The Collins Review will consult over the summer, asking how the reforms should be implemented, and will publish an interim consultation document for debate at this year’s party conference in Brighton. In addition, Miliband will launch a national campaign today, including a series of town-hall meetings, "to explain how Labour is changing".
Harriet Harman and Phil Wilson, who helped Blair reform Clause IV and who succeeded him as MP for Sedgefield in 2007, have been given "special responsibility" for debating the changes with party members. Alongside them, two key Miliband allies, Jon Trickett and Rachel Reeves, will examine what further reforms are needed to make Labour a mass membership party, drawing on the work begun under US community organiser Arnie Graf.
Miliband will say:
If we succeed in this then Labour has a historic opportunity to become a truly 21st Century party. A party powered by people, a party that can change a country that has a politics too often skewed to the interests of a wealthy and powerful few.
Britain’s working people don’t get to have cosy dinners in Downing Street to discuss policy, like David Cameron’s big donors. They don’t have lobbyists looking after their interests, like the big tobacco companies do with Lynton Crosby. Britain’s families don’t get enormous tax cuts, like the hedge funds and the millionaires.
That’s why they need a party that is open to them. That is on their side. A One Nation Labour Party for all the people of Britain, not just a few at the top. We’re going to build a new way of doing politics. We want to open up our policy-making, clean up the lobbying industry and take the big money out of politics. And we want to let people back in. So I want all Labour party members, supporters, trade union members involved in this dialogue, leading up the Special Conference this spring to agree change.
All of our country’s history shows that change does not come just from a few people at the top. Change comes when individual people come together to demand it. The Labour Party has a chance to help make that happen. To build a movement again. A movement that makes change happen in communities across the country. And a movement that changes Britain.
With so much attention on Labour's relationship with the trade unions, Lord Ashcroft, the Tory donor turned prolific pollster, has conducted a survey of Unite members, including how many would pay to join Labour. We'll have the results in full on The Staggers after the embargo ends at midnight.
