Donald Trump describes his relationship with Theresa May as "very, very strong", saying: "We really have a very good relationship."
Theresa May says of their meeting: "We're going to discuss the real opportunities we've got for a fantastic trade deal when we leave the European Union."
A spokeswoman for Theresa May says the prime minister will have a chance to bring Mr Trump "up to speed" on the UK's Brexit planning when they meet for talks.
"We are confident we can do a good trade deal with the US," the spokeswoman adds.
Meanwhile, both reacted when asked about the president's comments to The Sun newspaper.

"It was a very, very productive two days," says Donald Trump.
"We spoke for an hour, for an hour and a half, and it was really something. And today we are talking trade, we're talking military.
"We just looked at some incredible anti-terrorism things that are being done here in conjunction with the United States and the relationship is very, very strong. We really have a very good relationship."
Reality Check
Donald Trump says he is "the most popular person in the history of the Republican Party". BBC Reality Check asks if he is right.

We are facing a fascinating piece of political theatre at the press conference later.
You just wonder after last night when team May came out thinking all was well, then to pick up The Sun and read what Donald Trump has said about her Brexit approach - that in effect she has got it all wrong and crucially won't get a trade deal with the US - what the reaction will be.
And then, as if all that wasn't enough, he then goes out of his way to very publicly endorse Boris Johnson, Mrs May's arch-rival. It's hard to think of anything more likely to have Downing Street tearing out its hair.
In private there may be some frank talking, but in public I'd be very surprised if Mrs May sought to front up to Donald Trump.
Theresa May came out of Chequers to greet Donald Trump when he arrived at the PM's country home.
The US president walked up to shake her hand and told her: "It's nice to see you again."
They turned and posed for the cameras. He ignored shouted questions about the Sun article.
Speaking at Chequers, Donald Trump says he and Theresa May had "probably never developed a better relationship" than during last night's dinner at Blenheim Palace.
Melania Trump has joined children from Saint George's Church of England Primary School who were making Remembrance poppies.
She had a go at making one too and thanked the children for helping her.
Mrs Trump showed Philip May the poppy she had made, joking: "Very professional."

Donald Trump's criticism of Theresa May's Brexit strategy has sparked a backlash from UK politicians - including some government ministers.
The US President said the PM's plan would "probably kill" a UK-US trade deal.
He also said Boris Johnson would make a "great prime minister".
Some Conservatives are furious at his "divisive" remarks, but a prominent pro-Brexit backbencher thought what he said was "perfectly reasonable".
