Stand down! In a devastating blow to his authority, the prime minister lost a government motion by 272 votes to 285 – an opposition majority of 13 – after dozens of Tory MPs joined forces with Labour. A tally of votes compiled by the Labour whips found that 30 Tory MPs rebelled. Ministers had thought they were secure after a Labour amendment was defeated, in the first vote of the night, by 332 votes to 220, a government majority of 112.
One MP shouted “resign” as the results were read out by the Speaker. Cameron said within minutes of the result that the government would respect the decision of parliament which means that Britain will not take part in military strikes against the regime of Bashar al-Assad.
