David Cameron has been warned that UK air strikes against Isis in Syria could be illegal under international law.

In a briefing paper for MPs, officials said: “Action in Syria will be difficult to justify legally without a request for assistance from the Assad government, and it is unlikely that the West could be seen to be responding to such a request.
