British Prime Minister Theresa May said on Sunday that US President Donald Trump advised her to sue the European Union (EU) instead of negotiating over Brexit.

“He told me I should sue the EU — not go into negotiations. Sue them,” May said in an interview with the BBC. “Actually, no, we’re going into negotiations with them.”

May laughed off Trump’s comment, adding: "Interestingly, what the president also said at that press conference was ‘don't walk away.’

"Don't walk away from those negotiations because then you'll be stuck. So I want us to be able to sit down to negotiate the best deal for Britain."

Trump’s comments were made during a joint news conference on Friday, in which he said that May maybe found his advice “too brutal.”

While Trump thought that the British PM might eventually go with his “suggestion,” he said that “If they don’t make the right deal, she might very well do what I suggested that she might want to do.
