PMQs: Cameron and Miliband set out stalls on Europe
The referendum on Europe has dominated exchanges between David Cameron and Ed Miliband at a noisy prime minister's questions on 23 January 2013.
The prime minister has pledged to hold an in/out referendum on Europe if the Conservatives win the next general election, promising to renegotiate the UK's relationship with the EU before asking people to vote.
Labour leader Ed Miliband asked the prime minister if he would vote to leave the EU if negotiations with Brussels failed.
Mr Cameron told him he wanted a "strong Britain in a reformed Europe" which he said was right the country and the economy.
But Mr Miliband accused the PM of not answering the question, and asked him to "guarantee" he would vote "yes" in the referendum.
Mr Cameron said he would vote yes if the UK's aims are met, saying he does not want to "fail" in negotiations.
But he asked the Labour leader: "Does he have a clue what he would do?"
Mr Miliband said his party did not want an in/out referendum on Europe, and claimed Mr Cameron had been "dragged" into holding one by his eurosceptic Conservative backbenchers.
The PM told him to "go and get a policy on Europe", insisting that the referendum was in Britain's interest, and added "we will fight for it in the years ahead".
