Tory MP Sir Tony Baldry teased Ed Miliband over his campaigning as a teenager to leave the EEC (now EU) at the 1983 general election, when Labour was led by Michael Foot.

David Cameron said "we have to make room for everybody" about the leanings of the teenage Miliband, as he spoke about the UK's future relationship with the EU, and he took a swipe at the shadow chancellor.

The Conservatives have pledged to a hold a referendum on the UK's future in or out of the EU, but Labour does not back this.
