The memos described the Trump administration as “inept and incompetent” and sparked robust disapproval by Mr Trump who said he would not deal with the embattled diplomat. Mr Morgan was writing an opinion piece for Mail Online and began by quoting the dictionary definition of what a diplomat was. He summed it up: “In other words, it’s someone who knows how to build bridges, schmooze people, say all the right things and put out awkward fires when they erupt.”
Questioning why Sir Kim, who has been the ambassador in Washington since 2016, had not been fired, Mr Morgan said: “Short of standing outside the White House with a large placard saying ‘TRUMP SUCKS!’ it’s hard to imagine him failing in his primary duties more spectacularly.”
The former Daily Mirror editor voiced his fury after Prime Minister Theresa May had defended him: “Sir Kim decided it would be a smart idea to put down in electronic writing his very disparaging thoughts about the leader of his country’s No1 ally.”
The co-host of Good Morning Britain questioned Sir Kim’s intelligence: “Anyone with half a brain cell knows such incendiary, derogatory language would automatically send the thin-skinned President into a tailspin of fury.
“And anyone with even a quarter of a brain cell would also know that since Wikileaks detonated gazillions of similar diplomatic memos into the public ether several years ago, the likelihood of these particularly outspoken comments not leaking was extremely small.”

Questioning why Sir Kim had made the comments he said: “I suspect it’s because Darroch’s obvious personal dislike for the President overrode any diplomatic common sense.”
With the POTUS attacking both Sir Kim and Mrs May after the leaked memos were published, he also praised Mr Trump’s handling of the affair: “If anything, Trump has, unusually for him, understated things.”
With the Tory leadership contest expected to be settled in under a fortnight, Mr Morgan admitted despite Jeremy Hunt backing Sir Kim, Boris Johnson who has been noncommittal would sack Sir Kim “and rightly so”.
Mr Morgan questioned Sir Kim’s method of voicing his views: “If Sir Kim genuinely held such grievous concerns about the President of the United States, he should have imparted them to the Prime Minister in person.
“To commit them to a digital imprint knowing full well the inherent danger of doing so was incredibly dumb.”
Mr Morgan accused Sir Kim of wrecking the positive progress in the relationship between London and Washington built by Mr Trump’s state visit.
He concluded his piece by accusing Sir Kim of betraying British interests: “Sir Kim’s betrayed his own country too with his rank stupidity.”
This recent development was not the first time Sir Kim fell foul of diplomatic leaks.
Following the US election, a memo in which he told Mrs May that Mr Trump could be influenced by the British Government was also leaked.
In the memo, Sir Kim reportedly said: “The president-elect is above all an outsider and unknown quantity, whose campaign pronouncements may reveal his instincts, but will surely evolve and, particularly, be open to outside influence if pitched right.”
Sir Kim was Her Majesty’s Permanent Representative to the European Union under both Gordon Brown and David Cameron.
He also served as a National Security Adviser for Mr Cameron before being moved to replace Sir Peter Westmacott as the ambassador to the US.
