DAVID Cameron has been “rattled” by the support for Labour’s new leader so he is reverting to personal attacks a spokesman for Jeremy Corbyn said.

The Prime Minister accused the Labour leader of “hating Britain” and said he supported terrorists and would be a threat to the nation’s security.

Mr Cameron addressed the Tory Party conference in Manchester and said all you need to know about Mr Corbyn is he said the death of Osama bin Laden was a “tragedy”.

The Prime Minister said "No. A tragedy is nearly 3,000 people murdered one morning in New York. A tragedy is the mums and dads who never came home from work that day. A tragedy is people jumping from the towers after the planes hit.

"My friends, we cannot let that man inflict his security-threatening, terrorist-sympathising, Britain-hating ideology on the country we love."

Mr Cameron didn’t say the Mr Corbyn also said the attacks on the World Trade Center was a tragedy too.

What Mr Corbyn said in 2011 was “This was an assassination attempt, and is yet another tragedy, upon a tragedy, upon a tragedy.

“The World Trade Center was a tragedy, the attack on Afghanistan was a tragedy, the war in Iraq was a tragedy. Tens of thousands of people have died. Torture has come back on to the world stage, been canonised virtually into law by Guantánamo and Bagram.

“Can’t we learn some lessons from this? Are we just going to sink deeper and deeper?”

A spokesman for the Mr Corbyn said Mr Cameron's comments showed he was unnerved by the way the party had been re-vitalised.

He said: "The fact that David Cameron used his speech to make personal attacks on Jeremy Corbyn is a sure sign that he is rattled by the re-energisation of the Labour Party.

"With cuts to tax credits and a continued failure on housing, his claim that the Conservatives are the party of working people is being exposed."

Mr Cameron sued his conference speech, the first since the election victory, to claim the Conservatives were the party to protect people from poverty and to tackle extremism.

He said: “Over the next five years we will show that the deep problems in our society - they are not inevitable.”
