Donald Trump will offer the U.K. a quick and fair trade deal, the president-elect said in an interview with The Times newspaper published Sunday.

“We’re going to work very hard to get it done quickly and done properly. Good for both sides,” Mr. Trump said, adding that he planned to meet Prime Minister Theresa May soon after he gets into the White House.

The U.K. government won’t be able to sign any new bilateral trade deals until it has withdrawn from the European Union but it is free to scope out possible agreements before then. Mrs. May has said she plans to trigger the formal two-year process for leaving the EU by the end of March.

Mr. Trump, who has business interests in Britain, said he thought “Brexit is going to end up being a great thing” and welcomed the depreciation of the pound as helping to boost the attractiveness of British products abroad.

The president-elect, who will be inaugurated on Friday, said he understood the sentiment behind the campaign to leave the EU which he said believed was largely driven by immigration.

“I do believe this, if they [EU countries] hadn’t been forced to take in all of the refugees, so many, with all the problems that it…entails, I think that you wouldn’t have a Brexit. It probably could have worked out but this was the final straw, this was the final straw that broke the camel’s back,” he said and predicted other countries will leave the bloc.

U.K. Foreign Secretary Boris Johnson welcomed Mr. Trump’s comments.

“I think its very good news that the United States of America wants to do a good free trade deal with us and wants to do it very fast and it’s great to hear that from President-elect Donald Trump,” he said on his way into a meeting of EU foreign ministers. “Clearly it will have to be one that is very much in the interest of both sides but I have no doubt that it will be.”
