David Cameron will present his case to MPs later for the UK to begin airstrikes against so-called Islamic State in Syria. The PM will outline a seven-point plan which includes striking IS at its 'headquarters' in the Syrian city of Raqqa.
Prime Minister David Cameron has vowed to "make the case" for Britain to join the coalition carrying out airstrikes against the so-called Islamic State in Syria.
But such a move would raise other questions - including what would be done to help civilians still living in the country.
ITV News international affairs editor Rageh Omaar explains what could happen if MPs vote yes:
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".
Labour's shadow chancellor has said the notion of any UK intervention in the Syria conflict has to be looked at in a "very considered way".
