Prime Minister David Cameron has revealed he will "make the case" for Britain to join its allies in tackling the so-called Islamic State militant group in Syria in the House of Commons on Thursday.

David Cameron has revealed he will "make the case" for Britain to join its allies in tackling Islamic State in Syria, instead of just Iraq.
The Chancellor has said the government will only call a vote on UK military action in Syria when it is "confident that we are going to win".
