Gordon Brown, Tony Blair and John Major will all play a role in the campaign to keep Britain in the European Union - as will the Green MP, Caroline Lucas.
John Major, Tony Blair and Gordon Brown have all signed on to the cross-party campaign for a "Remain" vote in the forthcoming referendum on Britain's place in the European Union, in a coup for the Remain camp.
Voters will be asked to choose between "Remain" and "Leave" after the Electoral Commission ruled that a Yes/No question slanted the battlefield in favour of a Yes vote. In addition to signing up the three premiers, Caroline Lucas, the Green Party's only MP, will be on the campaign as well.
The In Campaign, which officially launches today, has also secured a number of celebrity and business supporters. Sir Stuart Rose, credited with turning around Marks & Spencers, will head up the campaign, alongside Apprentice star and West Ham vice-chair Karren Brady. June Sarpong, the television presenter, will also play a role.
