EU referendum: Cameron makes appeal to rebel MPs
The Prime Minister has appealed to Conservative MPs as he faces his biggest Commons rebellion since entering Downing Street.
Dozens of MPs could rebel against him and vote tonight for a referendum on Britain's membership of the European Union.
The vote is being seen as a test of David Cameron's authority, even though the Government is not expected to lose.
Deputy Political Editor James Landale reports.
