What Happens if Britons Choose to Leave the European Union?

Back in 2013, British Prime Minister David Cameron promised a referendum about the country's future in the European Union if he got re-elected in a national election this year, and now a vote on the issue is set for 2017 at the latest.

When Cameron pledged this to the people of Britain, he also made a list of demands for the EU. They no doubt satisfied many euro skeptics, but then Cameron had to deal with a cold shoulder from large EU countries like Germany and France.
