Countdown to vote on anti-IS strikes in Syria
MPs are divided ahead of a vote on whether to extend air strikes against Islamic State from Iraq to Syria.
Prime Minister David Cameron said there was "growing" parliamentary support for air strikes ahead of Wednesday's vote, saying it was "the right thing to do".
Meanwhile Labour leader Jeremy Corbyn said he looked forward to his MPs "being persuaded" to back his opposition to strikes.
