DONALD Trump's approach to foreign affairs is "beyond strange" and would leave the US a "totally isolated country", Jeremy Corbyn has said.
The Labour leader said the Republican presidential nominee had looked at the rest of the world and "wants to get off" it, but his plans to withdraw from global affairs would fail.
Both Mr Trump and Mr Corbyn have enjoyed success within their parties as a result of an anti-establishment swing, but the Labour leader rejected the comparison.
He pointed out he had "more in common with Bernie Sanders than Donald Trump, actually", in a reference to the outsider who took on Hillary Clinton for the Democratic nomination.
Mr Corbyn said White House hopeful Mr Trump's plans "can't work" but insisted there would be a close relationship between the UK and Washington whoever won the US election in November.
"I'm not confident that Donald Trump is going to win," he said.
He told BBC Radio 2's Jeremy Vine: "When I listen to Donald Trump, this is a man who seems to have decided that he has looked at the rest of the world, isn't very happy with it and wants to get off and wants America to be a totally isolated country.
"It's never worked in the past, it can't work in the future and whatever the outcome of the US election, obviously we are going to continue to have close relations with the USA,
"I find Donald Trump's approach to international affairs beyond strange.
"When he says that he doesn't want any trade treaties with anybody, because he thinks they are a bad idea, how on earth is the US going to trade with anybody? How's that going to work?"
