It has still not clear whether President Trump will make a “state visit” or a “working visit” to the UK, according to White House press secretary Sarah Sanders.
Mrs Sanders said: “We are still going back and forth with our allies there and once we have those travel details outlined and determined we’ll certainly let you know.
“But they have made the invitation for the President to come.
“We’ve accepted and we’re working out the logistics.
“We anticipate that it will be some time next year but at this point there are no other details beyond that.”

The US President was invited to visit the UK by Theresa May during a trip to Washington in January, shortly after he was inaugurated as President.
Earlier this year, angry members of the British public banded together to sign a petition that stated Mr Trump “should not be invited to make an official State Visit because it would cause embarrassment to Her Majesty the Queen”.
It was created in response to Mr Trump’s executive order to enforce a so-called “Muslim ban”, which led thousands of people to protest in London.
The online petition received over 100,000 signatures in just a few minutes and clocked up 1,863,708 signatures altogether.
Any petition that receives more than 100,000 signatures in the space of six months must be debated by MPs.
The petition was discussed in parliament on February 20.
Following the debate, the Foreign and Commonwealth Office said: “HM Government recognises the strong views expressed by the many signatories of this petition, but does not support this petition.
“During her visit to the United States on 27 January 2017, the Prime Minister, on behalf of Her Majesty the Queen, invited President Trump for a State Visit to the UK later this year.
“The invitation was accepted.
“This invitation reflects the importance of the relationship between the United States of America and the United Kingdom.
“At this stage, final dates have not yet been agreed for the State Visit.”
