SCOTTISH nationalists last night told Jeremy Corbyn they will help him get into No10 if he pledges to scrap Britain’s Trident nuclear deterrent.

SNP defence spokesman Stewart McDonald said the prospect of a snap election would be a “historic opportunity” to unilaterally disarm.

And he said it was a chance the lifelong anti-nuclear Labour leader would be “mad not to grab”.

Mr McDonald predicted his leader Nicola Sturgeon would make scrapping Trident a red line in any post-election pact to put Labour back in power.

Current Labour party policy is still to keep Trident amid fears among its trade union backers over the threat to thousands of defence jobs.

But Labour last month moved a step closer to officially adopting Mr Corbyn’s favoured unilateral nuclear disarmament policy.

Mr Corbyn’s ‘Peace Minister’ Fabian Hamilton has drawn up plans that would see a sweeping “defence diversification” project that would force skilled nuclear engineers to retrain as healthcare workers.

In an interview with the House magazine, Mr McDonald said: “I hope that if Jeremy’s in the position to form a government, perhaps with an arrangement with the Scottish National Party, then that [scrapping Trident] should be one of the key planks of any discussion that we have.

Because Corbyn agrees with us on this.

“He has a long and honourable history of agreeing with us on this.

“We’d ultimately have an opportunity, the first opportunity that would have presented itself in British history, for Britain to get rid of nuclear weapons.

We would be mad, and Jeremy Corbyn would be mad, not to grab that opportunity.”
