Jeremy Hunt, the Foreign Secretary and Mr Johnson's rival for the leadership, said in a statement: "l am deeply saddened by Sir Kim Darroch's decision to resign as Her Majesty's Ambassador in Washington".
"I was with Sir Kim last night in Washington". White Home officials said here's an example of the roughly treatment Darroch will doubtless receive within the aftermath of the leak.
Of course the biggest irony in those memos is Sir Kim Darroch's advice to diplomats - when they meet with the president they should "Start praising him for something that he's done recently". "Johnson's failure to back the British Ambassador in Washington makes him vulnerable to accusations of being weak towards Trump", Ford said on Wednesday.
"I do not know the Ambassador, but he is not liked or well thought of within the U.S", the president wrote on Monday.
While May gave her full backing to Darroch, her potential replacement as prime minister, Borish Johnson, declined to explicitly support the diplomat and instead emphasized the need for maintaining good ties with Washington.
'He has basically thrown this fantastic diplomat under the bus to serve his own personal interests'.
When asked whether it is relevant for a foreign leader to lambast the UK Prime Minister in such a rude way, Johnson said, "I don't want anybody else telling us what to do".
The UK's ambassador has stepped down from his post of Britain's ambassador to the United States after his candid conversation about Trump government got leaked.
Darroch, by contrast, served as the U.K.'s representative to the European Union from 2004 and 2007 and is widely seen as a europhile. On Wednesday, he expressed regret at Sir Kim's resignation and added that he hoped whoever leaked the e-mails "is run down, caught and eviscerated".
"It appears that uncertainties around trade tensions and concerns about the strength of the global economy continue to weigh on the United States economic outlook", he said.
Sir Kim resigned because he was anxious that "as long as he remained in Washington he would be a target, and his family with him", he added.
After learning of Darroch's assessment, Trump responded on Twitter by calling Darroch "a very stupid guy" and a "pompous fool". "If a foreign leader treated an American ambassador as President Trump treated the British ambassador, we would be up in arms, and justifiably so".
"This is not the first time a British ambassador has left post or resigned because of actions against the host government, but usually they are governments with whom we have problematic relations rather than friendly relations", McDonald said. Jonathan Powell, former prime minister Tony Blair's chief of staff, told Britain's Channel 4 News that the attempt to force Darroch from office followed similar efforts to punish career British officials suspected of insufficient enthusiasm for Brexit, according to The Intercept website.
"Friends speak frankly so I will: these comments are disrespectful and wrong to our Prime Minister and my country".
