AlQa'dah 22, 1436, September 06, 2015, SPA -- A majority of Britons now favour leaving the European Union amid concerns over immigration, an opinion poll showed on Saturday, signaling a shift in views ahead of a referendum on Britain's membership of the bloc, Reuters reported. The survey, by polling firm Survation for the Mail on Sunday newspaper, found 51 percent of respondents wanted to leave the EU and 49 percent wanted to remain, excluding undecided voters. While the results are within the poll's margin of error and represent a statistical tie, the previous comparable poll, carried out in late June and early July, had found support for staying in the EU at 54 percent while 45 percent wanted the country out of the 28-nation bloc. Prime Minister David Cameron has promised to renegotiate Britain's EU ties ahead of the referendum which is due to take place before 2017.
