Theresa May and Donald Trump will reportedly discuss slashing tariffs on UK-US trade when she becomes the first foreign leader to meet him on Friday.
The Prime Minister will be in Washington on Friday for talks which could be seen as the foundation of a new free-trade agreement post-Brexit.
The Daily Telegraph is speculating that moves to cut tariffs and ease visa restrictions on Britons will be discussed.
Mrs. May has claimed that Mr. Trump is looking for "early" talks on a deal, despite his "America First" strategy.
She told the BBC on Sunday: "He and the people around him have also spoken of the importance of a trade arrangement with the United Kingdom.
"That is something they are looking to talk to us about at an early stage, and I expect to be able to talk to him about this, alongside the other issues I will be discussing with him when I am in Washington."
Downing Street has said the meeting will serve as a chance for the two to "get to know one another" and "establish a productive working relationship" - though the Prime Minister has insisted she will tell the new president when she finds his behaviour unacceptable.
