No 'responsible' leader could ever leave EU, says Danny Alexander "David Cameron has said recently that a new consensus is necessary for our relations with Europe," Mr Osborne is reported to have told the newspaper, adding that the British people are currently "very disappointed" with the EU. Mr Alexander this morning told the broadcaster: "It was Margaret Thatcher who led the foundation of the European single market which is very important to British business and British jobs. That is why we have seen a lot of business leaders over the last last few days coming out very strongly and saying they want to see Britain's place in the EU maintained. Mr Alexander said there were "many reasons why Britain is an attractive place to invest." "But it is clear that for many sectors for many investors our place in the European single market, our participation as a leading member of the EU is part of that mix," he added. He insisted Mr Cameron had been "very clear he does not want Britain to leave the EU." Earlier Ed Miliband ruled out a referendum on Britain's membership of the European Union. The Labour leader said David Cameron's position on Europe is "incredibly dangerous" and that the Prime Minister is "sleepwalking us towards the exit door." "It's the wrong thing to do," he said on the BBC's Andrew Marr Show. Some Conservatives say Britain should leave the EU if other members do not agree to much looser membership.
