Ed Miliband: Britain 'sleepwalking' into EU exit

Britain is "sleepwalking" into leaving the EU, which would undermine the UK's economy and leave it "voiceless and powerless," Ed Miliband has said.

The Labour leader argued that Britain leaving Europe would be bad for the UK's prosperity and a "betrayal of our national interest".

But the Conservatives accused Labour of "opportunistic posturing" and not being "remotely credible" on the EU.
