http://www.telegraph.co.uk/news/worl...h-in-full.htmlIn a speech in central London, Mr Cameron said that it was time to "settle the question" of Britain's relationship with Europe.
He promised that his party's 2015 manifesto would ask for a mandate from the British people for a Conservative government to negotiate a new settlement with Europe.
"It will be a relationship with the Single Market at its heart," he said. "And when we have negotiated that new settlement, we will give the British people a referendum with a very simple in or out choice. To stay in the EU on these new terms; or come out altogether."
The EU is a confederation of 27 European states (7 more are expected to join in the future). There are many high ranking leaders within the EU (associated with a shady organisation known as the Union of European Federalists) that wish to turn it into a full-on federation.
David Cameron, the Conservative Party Prime Minister of the United Kingdom has, (after years of miserably failing to try and take powers from the EU back to the European states) agreed to hold a referendum on British membership of the European Union.
Currently, the polls are in favor of secession, with 47% of the British people supporting it. Many members of Cameron's own party have also campaigned for secession, such as MEP Daniel Hannan and MP Douglas Carswell. A secessionist third party, the UK Independence Party, lead by Nigel Farage, has polled well over the last few months.
Britain's main pro-EU center-left wing parties, the Liberal Democrat Party (the Conservatives' coalition partner) and the Labor Party have been critical of Cameron's move, as have pro-EU politicians on both the right and the left on the European mainland.
Cameron is expected to see a boost in the polls for his decision (the Labor Party's nominee is currently leading him by 13 percentage points.)
