'Very stupid guy,' Donald Trump renews attack on UK ambassador to US, Theresa May

The United States President Donald Trump renewed his attack on the UK's ambassador to Washington on Tuesday as he described him as "wacky", "very stupid" and "pompous fool". He also targeted British Prime Minister Theresa May as he said that the Brexit deal was a "disaster" because she went on "her own foolish way-was unable to get it done."

"The wacky Ambassador that the UK foisted upon the United States is not someone we are thrilled with, a very stupid guy. He should speak to his country, and Prime Minister May, about their failed Brexit negotiation," he said, adding, "And not be upset with my criticism of how badly it was handled."

"I told @theresa_may how to do that deal, but she went her own foolish way-was unable to get it done," Trump added in another tweet.

"A disaster! I don't know the Ambassador but have been told he is a pompous fool," he also said.

The tweet comes after the spokesman of British Prime Minister said that the UK ambassador to Washington, Kim Darroch, has May's full support.

London has been scrambling to stem the damage caused by the weekend release of confidential telegrams in which its envoy Darroch described the US leader as "inept" and his White House as "uniquely dysfunctional." 

He had also said that Trump's presidency could "crash and burn" and "end in disgrace", according to a cache of secret cables and briefing notes sent back to Britain seen by the Mail on Sunday newspaper.

The cables' publication in the Mail on Sunday newspaper came just a month after Trump enjoyed a state visit to Britain that included a 41-gun salute welcome at Buckingham Palace and a banquet dinner with the queen.

The incident threatens to complicate London's efforts to strike a new trade agreement with key ally the United States, in hope of mitigating potential damage from Britain's withdrawal from the European Union.
