Britain's ambassador to the United States resigned Wednesday, just days after diplomatic cables criticizing President Donald Trump caused embarrassment to two countries that often celebrate having a ``special relationship.''
The resignation of Kim Darroch came a day after Trump lashed out at him on Twitter describing him as ``wacky'' and a ``pompous fool'' after leaked documents revealed the envoy's dim view of Trump's administration.
``I am grateful to all those in the UK and the US, who have offered their support during this difficult few days,'' Darroch said in a letter. ``This has brought home to me the depth of friendship and close ties between our two countries. I have been deeply touched.''
Prime Minister Theresa May said it was a ``matter of regret'' that Darroch resigned.
Darroch's forthright, unfiltered views on the U.S. administration _ meant for a limited audience and discreet review _ appeared in leaked diplomatic documents that were published in Britain's Mail on Sunday newspaper.
Trump combined criticism of Darroch with a broadside at May, chiding the British leader for failing to get her Brexit deal with the European Union through Parliament.
``I told @theresa_may how to do that deal, but she went her own foolish way-was unable to get it done. A disaster!'' Trump tweeted Tuesday. ``I don't know the Ambassador but have been told he is a pompous fool.''
The resignation offers May a chance to replace him before she leaves office at the end of July.
