Corbyn: Tories are still the nasty party

Mr Corbyn will promise a Labour government would be “radical and responsible” as he officially launches the document widely leaked to the media last week.

The final document is expected to include a firmer line on immigration following pressure from shadow Brexit secretary Sir Keir Starmer.

Theresa May told Conservative activists in 2002 that they were known as "the nasty party" as she urged them to work to transform its image.

Mr Corbyn will say on Wednesday: "The Tories are still the nasty party. The party of prejudice, the party of the rich, the party of the tight-fisted and the mean-spirited."

The Labour leader will argue he is setting out "a programme that is radical and responsible".

He will say: “It’s a programme that will reverse our national priorities to put the interests of the many first. It will change our country while managing within our means.

“And it will lead us through Brexit while putting the preservation of jobs first.

“This is a programme of hope. The Tory campaign, by contrast, is built on one word: fear."

Mr Corbyn will repeat his challenge to the Prime Minister for a television debate

“What are you afraid of? It’s not too late. Let’s debate our two manifestos. Have the argument.

“I am confident that once the people of Britain have the chance to hear our promises and plans, they will decide now is the time for Labour," he will say.
