Miliband on 'Yes' vote platform
Labour leader Ed Miliband is to join former Liberal Democrat chief Charles Kennedy and the Green Party's Caroline Lucas on a cross-party platform to call for a Yes vote in the referendum on voting reform.
The event in Westminster on Tuesday will also involve several other leading politicians from Labour, the Liberal Democrats and the Greens, including Tessa Jowell and Baroness Shirley Williams.
Although both Labour and the Lib Dems officially support a Yes vote in the May 5 referendum on introducing the Alternative Vote for Westminster elections, there has been tension over whether their leaders would be willing to campaign together.
Mr Miliband has said he will not share a platform with Lib Dem leader Nick Clegg, advising the Deputy Prime Minister to "lie low" during the AV debate to avoid damaging the pro-reform camp's prospects.
A planned event which would have brought the Labour leader and Mr Kennedy together was cancelled earlier this month amid reports of behind-the-scenes disagreements over the line-up.
Announcing the press conference, Yes to Fairer Votes chair Katie Ghose said: "We're a people's campaign. We're all in this because we believe in politics. We welcome cross-party support to help us change the country's rotten voting system once and for all.
"We have volunteers out campaigning in every seat across the country. We have people who've never campaigned for any party - but we all understand this is our one opportunity to change politics, for good."
