Has already told the press he told May how to do Brexit but she ignored him. Quotes from - https://www.bbc.co.uk/news/uk-politics-44815558 Donald Trump has said the UK will "probably not" get a trade deal with the US, if the prime minister's Brexit plan goes ahead. He told The Sun the PM's plan would "probably kill the deal" as it would mean the US "would be dealing with the European Union" instead of with the UK. Mr Trump also said that former foreign secretary Boris Johnson would make a "great prime minister", adding "I think he's got what it takes". In his interview, he renewed his criticism of London Mayor Sadiq Khan over last year's terror attacks in the capital, saying he had done "a terrible job". He said the Brexit proposals Mrs May and her cabinet thrashed out at Chequers last week mean it would be "most likely ... we would be dealing with the European Union instead of dealing with the UK, so it will probably kill the deal". He also said he had told Mrs May how to do a Brexit deal, but: "She didn't agree, she didn't listen to me." "I told her how to do it. That will be up to her to say. But I told her how to do it. She wanted to go a different route," he said.
