Shadow foreign secretary Hilary Benn has shown public support for Britain carrying out airstrikes in Syria after a shadow cabinet minister told ITV News a "clear majority" of the shadow cabinet was in favour of backing the Prime Minister's plan.
Mr Benn said there were "compelling arguments" for RAF strikes in Iraq being extended into Syria.
We are trying to make life difficult for Isil/Daesh in Syria and I think there's a very strong case for us playing our full part in doing that, given that we are currently flying missions, providing intelligence and refuelling to others who are participating.
I think our allies look to us - particularly the French, after the grievous blow they have suffered in Paris - and they want to feel we are with them in solidarity, and I think we should be.
Mr Benn's shadow cabinet colleague Diane Abbot, though, said she was "not sure (air strikes) would make British people safer at all".
