Ilford South MP Mike Gapes and Romford MP Andrew Rosindell have said they will be voting in favour of air strikes against Islamic State – formerly ISIL – militants in northern Iraq.

But Mr Gapes said the current motion “does not go far enough”.

He said: “To defeat the criminal IS caliphate cult we need a broad international coalition including action by Arab forces on the ground against ISIL in Syria as well as Iraq.”

And John Cryer, MP for Leyton and Wanstead, said he would also be supporting intervention against IS, also known as ISIS.

He said: “10 years ago I voted against the Iraq war seven times but this is different.

“IS are modern-day Nazis, they have slaughtered Moslems, Christian and Yazidis alike.”

“I don’t do this with any pleasure and am still uneasy about intervention but without previous air strikes it seems likely that this bunch of bloodthirsty, sadistic gangsters would be in Baghdad.

“They already control are area larger than Britain and their further territorial ambitions are clearly a matter of record.

“If they had the equipment they would be building gas chambers.”

Lee Scott, MP for Ilford North, said he would not be at the debate because of the Jewish New Year.

But he said he had been paired with a Labour MP, and if present he would have voted for the motion.

Romford’s Andrew Rosindell MP said he would also be supporting the vote.

The Conservative MP said: “While it is right that the UK has already offered support to the Iraqi government and Kurdish ground forces in terms of resources, and has assisted fleeing minority groups with humanitarian aid drops, this must be coupled with air strikes in order to maximise the effect.

“Britain has unique military capabilities and it is wrong to stand idly by whilst innocent civilians are being mercilessly slaughtered by barbaric terrorist thugs. I will be supporting the Government in this vote.”

Earlier today, Prime Minister David Cameron signalled he would be prepared to extend strikes to include Syria.

MPs are expected to give overwhelming backing in the vote, which takes place at 5pm, for Britain to join US-led strikes.

If successful, the RAF would begin raids this weekend.
