During the 2015 Labour Leadership at a party hustings in Warrington, in July 2015, Corbyn speculated that, should David Cameron be unable to protect workers' rights and environmental protection laws in his negotiations with European leaders, he would be prepared to support a 'No' vote in the proposed referendum on EU membership. What if Corbyn is more openly pro-Brexit and states that he personally would vote to Leave the European Union. Does he still win the election or do his more newer younger backers get cold feet?.
