Labour leader Jeremy Corbyn has risked sparking fresh controversy after blaming the rise of ISIS on Britain and the United States.

The veteran anti-war campaigner said ISIS hadn't 'come from nowhere' and was partly 'a creation of Western interventions in the region'.

Mr Corbyn, 66, said attacking the fanatical group would only make things worse and instead claimed Britain would be safer it if declared that it supported the 'diversity of faith and diversity of aspirations around the world'.

The remarks round off a turbulent week for Mr Corbyn after overseeing chaotic cabinet reshuffle culminating in a public u-turn over Labour's position on the European Union.

Mr Corbyn was roundly condemned on Tuesday for refusing to sing the national anthem at a memorial to Battle of Britain heroes.

The veteran socialist, speaking to the obscure website 'Middle East Eye', said Labour needed to stick to its 'principles' and vowed to stay on as Labour leader for the next five years.

But he risks a major rebellion over a proposed vote on extending the military action against ISIS into Syria.

The Prime Minister has called for a 'political consensus' in favour of authorising military strikes before calling a vote in Parliament.

Mr Corbyn was roundly condemned on Tuesday for refusing to sing the national anthem at a memorial to Battle of Britain heroes

In 2013 Mr Cameron was left humiliated after MPs - including Mr Corbyn - rejected airstrikes. Speaking today, Mr Corbyn said he would not change his position.

Mr Corbyn said: 'ISIS did not come from nowhere. They have got a lot of money that's come from somewhere.

'They've got a huge supply of arms that have come from somewhere. They are – not in total, but in part – a creation of Western interventions in the region.

We make ourselves safer by saying we understand the diversity of faith and diversity of aspirations around the world Jeremy Corbyn

'What I would do is try to economically isolate them. And also try to unite the other groups in the region by supporting autonomy for the Kurdish groups and recognise the vast amount of arms that we have sold – particularly to Saudi Arabia – end up somewhere and those are now being used.

'Bombing by the West in Syria now would create more mayhem. It's very unclear who the alliances would be with and it would make the situation worse.

'I opposed the bombing of Syria in that historic 2013 vote and would continue that position.'

Despite his position Mr Corbyn insisted he would keep Britain safe.

He said: 'We make ourselves safer by not being part of US foreign policy at every single turn.

'We make ourselves safer by saying we understand the diversity of faith and diversity of aspirations around the world.

'And also by becoming a force for human rights rather than military interventions around the world.

'I think that would make us safer.'

The Prime Minister last week made clear he would push ahead with a vote on air strikes - possibly as early as next month

Mr Corbyn has previously sparked fury by comparing ISIS brutality to US military action in Iraq.

The Labour leadership frontrunner called for 'acceptance and understanding' of ISIS supporters while speaking on Russia Today, the Kremlin-backed broadcaster, in June last year.

He only condemned 'some' of the brutal regime's actions in Iraq, saying: 'Yes they are brutal, yes some of what they have done is quite appalling, likewise what American forces did in Fallujah and other places is quite appalling.'

Despite Mr Corbyn's staunch opposition to military actions against ISIS, the Prime Minister last week made clear he would push ahead with a vote on air strikes.

He roundly dismissed the suggestion that the new Labour leader might be able to block extending military action across the border.

On a visit to Lebanon and Jordan where he met refugees fleeing from the Syrian civil war, the PM was asked whether Mr Corbyn's election meant ministers were further away from pushing for a vote.

Mr Corbyn said he was 'unclear as to the point of killing' British ISIS fighter Reyaad Khan (above) in a secret operation on August 21

He told journalists: 'That will depend on Parliament. It doesn't necessarily depend on the views of one person'.

His comments gave the strongest signal that ministers are preparing to push ahead with a vote on bombing raids regardless of the election of the pacifist Left winger on Saturday.

The government is expected to reach out to disaffected Blairites and defence hawks within Labour to secure the backing of the House of Commons.

At the moment RAF pilots are engaged in bombing raids against Islamic State within Iraq but cannot pursue their enemies across the border or launch raids against IS strongholds within Syria.

There is widespread speculation a vote on bombing raids could take place as early as next month.

Mr Corbyn is expected to vote against - a move which would leave him open to further Tory attacks on his security record.

Before being crowned Labour leader Mr Corbyn attacked the PM for launching a drone strike which killed a British ISIS fanatic.

The veteran socialist said was 'unclear as to the point of killing' terrorist Reyaad Khan in the secret operation on August 21.

Mr Corbyn questioned whether the RAF airstrike which killed Khan and a fellow UK jihadist Ruhul Amin was legal and confirmed he would not have authorised the attack.

The Prime Minister stunned MPs on Monday by revealing the UK had used military force in Syria without parliamentary authority and against a Briton.

Mr Cameron said: 'There was a terrorist directing murder on our streets and no other means to stop him.'

A third British fanatic, Junaid Hussain, was killed three days later by a US drone in a joint operation with the UK.

The revelation that Khan, 21, from Cardiff, had been assassinated in the first RAF drone strike against a Briton triggered claims of extra-judicial killing. But Mr Cameron insisted the attacks were an act of self-defence and entirely legal.

He said Khan and Hussain were orchestrating attacks on 'high-profile public commemorations' over the summer from the IS stronghold of Raqqah.

Targets included VJ Day last month and the VE day commemorations of May 8. The commemorations were attended by scores of war veterans and dignitaries – including the Queen.

It's all going very well: Corbyn's first week in charge dominated by rows, splits, gaffes and at THREE u-turns

By Matt Chorley, Political Editor

Say what you like about Ed Miliband but it took him years to get in the sort of mess that Jeremy Corbyn has managed in a week.

Supporters of the new Labour leader have spoken enthusiastically about what he will achieve in his first 100 days.

But if his first 100 hours in the job were anything to go by, some will be left wondering if he will even last that long.

The catalogue of blunders, mis-steps and self-inflicted wounds is long already - and growing.

Rambling victory speech

Mr Corbyn;s acceptance speech was long and rambling, without any clear message for the headline writers

Mr Corbyn at least managed to look a bit smarter than usual - thanks to a new jacket bought by his sons - but his acceptance speech was long and rambling, without any clear message for the headline writers.

Perhaps it was no surprise that Labour staffers turned up for the announcement wearing black.

He seemed more at home signing the socialist anthem The Red Flag in a pub and later at a refugee rally in Parliament Square.

Media melt-down

For most new party leaders the chance to set out your stall to the nation is not one to pass up.

But Mr Corbyn is no ordinary leader. He ducked out of a planned appearance on the BBC's flagship Andrew Marr show to attend a mental health fun day in his constituency, where he posed for photos with supporters and a group of Bollywood dancers.

He then declined to appear on BBC Radio 4's Today programme, leaving his leadership to be defined by others.

Policy split #1: Europe

Chuka Umunna reveals on Sunday night that he left the frontbench after Mr Corbyn said he could campaign for Britain to leave the EU.

On Monday morning, shadow foreign secretary Hilary Benn insists: 'We will stay to fight together for a better Europe'.

But then on Monday night Mr Corbyn told a meeting of Labour MPs he would not give David Cameron a 'blank cheque'.

Shadow justice Lord Falconer threatened to resign if Labour did not back staying in the EU, quickly followed by Alan Johnson, who is due to lead Labour's In campaign.

Shadow chancellor wants to 'overthrow capitalism'

The appointment of IRA sympathiser John McDonnell as shadow chancellor caused dismay in the party, with shadow foreign secretary Hilary Benn refusing to welcome the move when he appeared on Radio 4.

Silence is not so golden #1

In a bizarre 2-minute video of Mr Corbyn leaving Parliament on Sunday night, he refused to answer questions about his leadership or reshuffle.

Instead he walked along the pavement staring straight ahead, until complaining: 'These people are bothering me.'

Men get plum roles, women get 'made up or s*** jobs'

The reshuffle descended into chaos when several people turned down jobs, and it emerged the four Great Offices of State - leader, Chancellor, Foreign Secretary and Home Secretary - were to be shadowed by women.

While Mr Corbyn boasted that half of his top team were women, but critics said he had only reach the target by giving them 'made up or s*** jobs'.

Policy split #2: Defence

Mr Corbyn wants to scrap Trident, have Britain leave Nato and opposes military actions against ISIS in Syria.

Most of his Labour MPs do no agree. Within hours of his victory, deputy leader Tom Watson made clear his opposition to the policies.

There was then a scramble to find a shadow defence secretary as Vernon Coaker and then Chris Bryant said they disagreed with the leader's stance.

Finally, it was confirmed today that Mr Corbyn had backed down and had appointed an overwhelmingly pro-Trident shadow defence team.

Silence is not so golden #2

Refusal: As those around him including Defence Secretary Michael Fallon (far left) , Air Chief Marshal Sir Andrew Pulford (second left) and wife Lady Nicola (third left) sang the national anthem today, the pro-republican leader of the Labour Party Jeremy Corbyn stood silent

Sparks fury with his refusal to sing the National Anthem at a memorial service to remember the heroes of the Battle of Britain on Tuesday.

Labour HQ confirmed that the republican had chosen to remain tight-lipped, but frontbenchers Owen Smith and Kate Green condemn the decision.

Forgetting Margaret Thatcher

In an attempt to show the Labour machine was still capable of appearing professional, the press office released extracts of what Mr Corbyn would say to the TUC conference in Brighton.

The 20-minute quick-fire address to delegates in Brighton, delivered tieless, was originally intended to include a passage invoking Margaret Thatcher's 1980s phrase to warn that the Conservatives still regard unions as 'the enemy within'.

However, Mr Corbyn did not deliver the pre-briefed lines, with Labour officials saying he was working from notes and simply 'forgot'.

It was four years into Ed Miliband's leadership before he missed out the key passage on the deficit. Mr Corbyn managed it in under four days.

Taking the money and the car

Despite claiming to live a simple life and hating cars, Mr Corbyn is expected to take most of the £58,000 pay rise on offer as leader of the opposition and make use of the official car - paid for by the taxpayer.

He will also swear allegiance to the Queen in order to join the Privy Council.

Policy split #3: Benefits

In his TUC speech, Mr Corbyn announced he would scrap the benefit cap - to the dismay of Labour frontbenchers

One thing Mr Corbyn did not forget in his TUC speech was a big announcement on welfare: he would scrap the benefit cap.

Unfortunately, his own frontbench do not agree - not least because the Tory limit on welfare claims is hugely popular with voters.
