The refugee crisis is the biggest challenge facing Europe since the Second World War. Millions of people have fled the conflicts in the Middle East and many are now in Europe. Dealing with this crisis will require international coordination, with all European countries playing their part.

There is no doubt that Isil poses a serious threat to our national security. They have carried out terrorist atrocities in France, Turkey, and against many of our other allies. Our intelligence agencies have foiled a number of planned attacks on the UK in recent years. That is why it is right that we are acting, along with our international partners, to confront this barbaric organisation.
