President Donald Trump promised the U.K. a "phenomenal trade deal" Tuesday, on the second day of his state visit to Britain.

His comments revealed little detail but added to previous assurances from the U.S. president as Britain slowly edges toward an exit from the EU.

"As the U.K. makes preparations to exit the European Union, the United States is committed to a phenomenal trade deal between the U.S. and the U.K.," Trump said at a joint press conference with U.K. Prime Minister Theresa May.

"There is tremendous potential in that trade deal — I say probably two and even three times of what we are doing right now," Trump told reporters after meeting May for talks which lasted an hour.

Trump added that he thought Brexit will happen and should happen, responding to questions on the current impasse in Westminster which has helped to topple May who is stepping down as Conservative Party leader on Friday.

The talks with May on Tuesday involved a variety of contentious topics, which included climate change, trade and tensions with Iran. The U.K. is not allowed to open official trade talks with other nations until it has fully left the bloc.

May's Brexit deal with the EU has been rejected three times by U.K. lawmakers and the deadline for Britain's departure has now been pushed back to October 31 while a leadership contest — and potentially even a general election — takes place.

Trump said Tuesday that anything was on the table with regards to a U.S.-U.K. trade deal and said May had done a very good job with Brexit and deserved a lot of credit.

The pound was little changed against the dollar on Tuesday afternoon as both leaders spoke.
