Labour leader said the rise of Euroscepticism within the UK was causing "alarm" with partners across the bloc. He said being part of Europe was good for British business, and any exit would be a betrayal of the national interest:
"I will not let Britain sleepwalk to an exit from the European Union, it would be bad for prosperity"
He said the "reasons for scepticism are real" and it was up to leaders to tackle the questions raised about the problems of the single currency:
"Scepticism about the euro and the project undermines the case for the wider European Union"
