Nick Clegg echoes call for action on IS in Iraq

Deputy Prime Minister and Liberal Democrat leader Nick Clegg told the BBC his party would support air strikes in Iraq.

He said they were "legal" and the UK would be "part of a much bigger coalition, a whole array of countries, crucially including a number of Arab countries which deprives Isil of the ability to somehow portray it as a west verses the rest crusade".

Parliament is to be recalled on Friday to discuss the UK's possible involvement in air strikes against Islamic State (IS) in Iraq.

Prime Minister David Cameron said MPs should respond to the Iraqi government's request for help.
