Trump, during the trip, is supposed to visit Buckingham Palace and then travel to France for the 75th anniversary of D-Day, Sky News Broadcasting reported on Monday.
While the exact date of the visit is unclear, there is speculation it could take place around 6 June, according to The Daily Express.
When in the UK, Trump is expected to attend the Horse Guards Parade in London and inspect the Guard of Honour before arriving at Buckingham Palace where a State Banquet in the Ballroom, accommodating about 150 VIP guests, is due to be held.
This would be Trump's second trip to the UK, following the four-day visit he made last July, when he was met by thousands of people protesting his policies.
In July 2018, Trump travelled to the UK for a two-day working visit, during which he met Prime Minister Theresa May at Blenheim Palace and also sat down with the Queen for tea at Windsor Castle.
