Cameron: Corbyn's Labour 'A Security Threat'

David Cameron has called the Labour Party "a threat to national security" after left-wing Jeremy Corbyn was elected leader.

Mr Corbyn stormed to an overwhelming victory in the party's leadership race on his anti-war, anti-austerity platform.

But the Prime Minister has warned in a tweet: "The Labour Party is now a threat to our national security, our economic security and your family's security."

Before the veteran MP's triumph on Saturday, Mr Cameron warned he would be a bad opposition leader for Britain as he would break a consensus between the main parties on issues like nationalisation, nuclear weapons, taxation and union laws.

"The country is stronger when you have shared objectives rather than when you've got someone who wants to take us back to the days of Michael Foot and Arthur Scargill," he said.

Mr Corbyn is currently putting together his first shadow cabinet , which will work to unite the party behind his policies.

And then he will face Mr Cameron for the first time since becoming leader at PMQs on Wednesday.

As soon as he was elected, Mr Corbyn appealed to his supporters to suggest what they would like him to ask him at the weekly Commons clash.

Senior Tory MP David Davis told Sky's Murnaghan programme that Mr Corbyn's win likely improved Conservative chances of another term in office - but he warned against "complacency".

"I think the odds of our winning the next election after yesterday are higher but I don't think it's an open-and-shut case by any means," he said.

"Complacency will be absolutely the daftest thing to go in for now."

But he said personal attacks on the new Labour leader would backfire.

"The risk, as happened with [Nigel] Farage actually, lots and lots of personal attacks on Farage completely bounced off and they were far more personal actually than some of the things we've heard about Jeremy Corbyn and they just bounced off," he told Sky News.

"They bounced off because he's seen as an anti-establishment, non-conventional figure."

Justice Secretary Michael Gove also said his party should not be "gleeful" and must "face up to the reality" that Mr Corbyn may well be prime minister one day.

"It is because of that that we have to lay out at this time the scale of the risk that would be posed to Britain," he told BBC1's Andrew Marr Show.

"The people he calls friends in the international sphere are the terrorist organisations Hamas and Hizbollah."

A snap poll also suggests Mr Corbyn has a lot of ground to make up if he is to pose a threat to the Prime Minister.

Only 27% see him as prime ministerial compared to the 44% who endorse Mr Cameron, the Survation poll for the Mail on Sunday said.

The survey was carried out immediately after the leadership result was announced on Saturday.
