Sir Darroch resigned in July last year after leaked documents revealed the diplomat had called the Trump administration “clumsy and inept”. Mr Trump responded at the time by calling Sir Darroch “a very stupid guy”.
The ambassador then announced it would be “impossible” for him to continue in his role.
Now, Mr Trump’s former national security advisor John Bolton has revealed just how angry the president was at the UK ambassador’s comments.
Mr Bolton told The Telegraph: “The hardest US-UK issue really was when some of the cable back from the UK ambassador became public.
“I think the morning they appeared Trump called me and said ‘get him out of here’.
“I mean at like seven in the morning or six in the morning. Early. I was at the office but even for Trump that was early.”
Mr Bolton also revealed Sir Mark Sedwill – then the UK’s top civil servant – was reluctant for Sir Darroch to resign.
The security expert said Sir Sedwill “obviously” did not want to pull Sir Darroch out of his US post.
However, he warned “things are going to get worse” if the former ambassador remained.
The former ambassador made his remarks in a series of secret memos he sent to Downing Street.
Sir Darroch is reported to have said in the summer of 2017: “As seen from here, we really don’t believe that this administration is going to become substantially more normal; less dysfunctional, less unpredictable, less faction-riven, less diplomatically clumsy and inept.”
He is also claimed to have said: “For a man who has risen to the highest office on the planet, President Trump radiates insecurity.”
In later remarks, Sir Darroch said there was a “credible path” for Mr Trump, but that it heavily depended on who the Democrats chose to oppose him this year.
The Democrat nominee – Joe Biden – currently leads in US polls, according to Real Clear Politics.
Voters in the US are due to decide on November 3 who the next US President will be.
The run-up to the vote has been marred by Mr Trump’s unsubstantiated claims that mail-in voting is fraudulent and could result in an unfair election.
