All but one of 28 economists in the poll taken this week said the Britain would take a hit if the vote - which could take place by June - meant exiting the EU.

European Union leaders could clinch a deal with British Prime Minister David Cameron in February to prevent the bloc\'s second largest economy leaving, European Council President Donald Tusk said on Thursday. Cameron is seeking to renegotiate Britain\'s relationship with the bloc it joined in 1973 ahead of a referendum on membership to be held by the end of 2017. Some EU leaders are wary of agreeing to all of his demands, however, particularly on cutting benefits for EU migrants to Britain. REUTERS/Luke MacGregor (credit:Luke MacGregor / Reuters)

British Expats And Germans Discuss Brexit(13 of13)
Open Image ModalBERLIN, GERMANY - MAY 26: European Union (L) and British Union Jack flags hang at a meeting for British citizens living in Germany to discuss the implications of Great Britain leaving the European Union, known popularly as Brexit, on May 26, 2016 in Berlin, Germany. On June 23, 2016, UK citizens will vote on a post-legislative referendum on the country\'s membership in the European Union. Many British proponents of leaving the EU argue that it would allow the UK to better control immigration as well as save billions in membership fees as well as control trade deals and legislation, while those who wish to remain believe that leaving would decrease both the country\'s influence in world affairs as well as its security, and cause trade barriers with the rest of Europe.
