Cameron faces embarrassment over EU vote

British Prime Minister David Cameron yesterday faced his first major test from within his own party as eurosceptic backbenchers threatened to defy him in a vote on an EU membership referendum.
Yesterday's vote in the lower House of Commons is non-binding but politically significant with up to 85 Conservative lawmakers tipped to ignore Cameron's order for them to vote against any referendum.
The Liberal Democrats, The government's junior coalition partners, and the main opposition Labour party are both expected to vote with Cameron, so defeat is highly unlikely but victory will only expose the extent of the Tory rebellion.
Cameron has imposed a three-line whip, which usually results in dismissal for any member of the government who votes against it and presents a large obstacle in the career path of any rebel backbench MPs.
