Jeremy Corbyn ended his election campaign by warning voters they are at a “fork in the road” between radical change under Labour, and a Boris Johnson government that would “continue destroying our public services”.

The Labour leader closed a whirlwind eve-of-poll tour of marginal constituencies starting in Glasgow, with a rally in a packed warehouse venue in Hackney, east London.

Having earlier insisted Labour would win Thursday’s vote “no problem at all”, despite polls heavily suggesting otherwise, Mr Corbyn stressed the “very profound” issues at stake.

“We’re literally at a fork in the road,” he told a young audience of hundreds as he ran through the best hits from his manifesto.

“So when the election comes tomorrow it is a very clear choice. You go down the road of Boris Johnson, a sweetheart deal with Donald Trump, we break off any serious relationship with Europe.

“Or you go down the Labour way, which is the adult, responsible way, of negotiating a settlement which we will all live by, and I will make sure is carried out in a future relationship with Europe.

“But we also go down the road of investing in our country, investing to end austerity and redistributing wealth and power in our society in a way that’s never been seen before.”

While the confirmatory referendum policy within six months was met with silence from the young audience, the message on radical change was widely cheered and applauded.

He warned of negotiations to sell off the NHS in post-Brexit trade talks, adding: “That is what Boris Johnson would continue doing if elected again on Friday, destroying our public services on the altar of a global free market dominated by a small number of multinational companies.”

Labour’s chances of success looked to be fading when a YouGov poll suggested the Conservatives were on course for a 28-seat majority despite their lead narrowing.

But Mr Corbyn, while refusing to comment on the poll directly, was defiant in predicting Labour would still cruise to victory during an interview after a rally in Middlesbrough.

“Of course we are going to do it – no problem at all,” he said.

Saying that the “only poll that matters is the one tomorrow”, he said victory would come because Labour’s “message of hope” was being heard by voters despite a “relentless media assault”.

He declined to say whether he would resign if Labour does not get the victory he was forecasting.

“I think you should concentrate on the election and the fact that Labour is going to win the election,” he said.

He also seized the opportunity to mock the Prime Minister, who had earlier entered a fridge while being pursued by an inquisitive reporter.

“I’ve not come here to deliver milk, or to hide in a fridge,” Mr Corbyn said during the rally. “I’ve come here with a message of hope.”
