Britain goes to war on ISIS: UK Parliament backs air strikes in Iraq against 'psychopathic terrorists' but not in Syria

Britain is to join air strikes against ISIS militants in Iraq after MPs voted overwhelmingly by 524 to 43 to back military action.

Six RAF Tornados are expected to join war planes from the US, France and Arab nations after Parliament staged a six-hour emergency debate on UK intervention.

David Cameron insisted Britain cannot 'walk on by' in the face of the threat posed by 'psychopathic terrorists'.

But divisions emerged over expanding action into neighbouring Syria, with Labour leader Ed Miliband insisting a UN Security Council resolution should be sought first, even though Russia and China are certain to veto it.

MPs backed the Government's plans to join air strikes against ISIS in Iraq by 524 to 43 - a majority of 481 - after more than six hours of debate in an emergency recall of Parliament today
