Donald Trump has said the US and Britain are “rapidly” moving towards a post-Brexit trade deal that will be “fantastic and big”.
The US President said he and Boris Johnson are “very much aligned” and will continue to discuss the potential agreement.
Speaking ahead of a campaign rally in New Hampshire, Mr Trump said talks with the Prime Minister are “moving rapidly along”.
"I think we'll make a fantastic and big trade deal with the UK," the US leader told reporters before departing for the rally on Thursday.
He said he had talked to Mr Johnson on Wednesday and would be speaking with him again.
"He and I are very much aligned," Mr Trump added.
It comes after Mr Johnson said he expects reaching a post-Brexit trade deal with the US to be a “tough old haggle”.
He said: "In my experience the Americans are very tough negotiators indeed, and we will do a great deal with them and it will open up opportunities for UK business, particularly service companies in the US, but it will be a tough old haggle - but we will get there."
The two countries are discussing a partial accord that could take effect on November 1, the day after the UK is set to leave the EU.
Officials from the two nations have discussed the possibility of a temporary agreement covering all sectors.
Such a deal could last for something like six months, a senior Trump administration official said on Tuesday.
Mr Trump’s national security adviser said the UK was “first in line” for such an agreement with the US.
John Bolton said the US could focus on striking bilateral trade deals in certain sectors like manufacturing and car-making where the two countries may agree, and work out more complicated areas later.
Speaking following a meeting with Mr Johnson on a visit to London, Mr Bolton said in the eyes of the president “Britain's constantly at the front of the trade queue, or line as we say.”
