Cameron calls for one-day debate, parliamentary vote over air strikes in Syria

British PM David Cameron is to ask his cabinet to endorse a one-day Commons debate and vote on Wednesday over UK air strikes against so-called Islamic State in Syria.

David Cameron said there was "growing" parliamentary support for air strikes, saying it was "the right thing to do" and in the national interest.

Labour leader Jeremy Corbyn is granting his MPs a free vote on the matter. He has criticised the decision not to hold a two-day debate, saying Cameron should "stop the rush to war".

Cameron said he would recommend that a debate and vote is held to extend air strikes against Isil in Iraq to Syria in order to "answer the call from our allies and work with them, because Isil is a threat to our country and this is the right thing to do".

Prior to Cameron's statement, Corbyn called for two days' of debate ahead of any vote, saying a single day "would inevitably lead to important contributions being curtailed".

But Cameron - who was speaking in Downing Street shortly after returning from the Paris climate summit - said there would a "very long and full" debate.

"We will take the action necessary to make sure we have, in many ways, the equivalent number of questions we would often have across a two-day debate in one day," he said.

"I want MPs to be able to have full consideration, to make speeches, to make points, to ask me questions, to examine the government's case," he added.
