Donald Trump has launched a fresh attack on Theresa May and the UK’s ambassador to the US as he called the Prime Minister a ‘disaster’ and labelled Sir Kim Darroch a ‘pompous fool’.
The US President described Sir Kim as a ‘very stupid guy’ who had been ‘foisted upon the United States’ as an unprecedented row between the White House and the British government escalated.
Last night Mr Trump said Mrs May had made a ‘mess’ of Brexit and today he went even further as he called the Prime Minister ‘foolish’.
His comments are likely to add fuel to the fire of what was already an incredibly damaging row between the two old allies.
Mr Trump tweeted: ‘The wacky Ambassador that the U.K. 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, and not be upset with my criticism of how badly it was handled.
‘I told how to do that deal, but she went her own foolish way-was unable to get it done. A disaster! I don’t know the Ambassador but have been told he is a pompous fool.’
Downing Street has been trying to repair the damage done by the leak of diplomatic memos which saw Sir Kim label Mr Trump ‘inept’.
But Number 10 has stuck by the veteran diplomat with Sir Kim continuing to enjoy the ‘full support’ of the Prime Minister.
However, with Mrs May set to leave office in just two weeks, her replacement could be faced with a major headache as soon as they take office.
If the next PM decides to keep Sir Kim in post then relations with the White House are likely to continue to deteriorate.
But if Mrs May’s successor opts to replace Sir Kim they will face accusations of being in the pocket of the US President.
Mr Trump’s latest comments came after it emerged Sir Kim had been frozen out of two major events by the Trump administration in a brutal snub.
Sir Kim has been excluded from a business meeting between International Trade Secretary Liam Fox and Ivanka Trump today after he was dis-invited from a lavish White House dinner for a gulf potentate last night.
He was barred from the posh event for the Emir of Qatar after the American president said that he will ‘refuse to deal’ with the ambassador after the leak of the bombshell cables.

Secret cables leaked to The Mail on Sunday over the weekend showed Sir Kim had said that the White House would likely ‘never look competent’ under Mr Trump.
It prompted a tweet on Monday night in which Mr Trump said Sir Kim was ‘not well thought of’ in the US as he vowed to no longer do business with him.
He also criticised Mrs May’s handling of Brexit and said she had made a ‘mess’ of talks with Brussels.
‘I do not know the Ambassador, but he is not liked or well thought of within the US,’ he said.
‘We will no longer deal with him.’
‘The good news for the wonderful United Kingdom is that they will soon have a new Prime Minister,’ Trump continued.
‘While I thoroughly enjoyed the magnificent State Visit last month, it was the Queen who I was most impressed with!’
At Monday night’s dinner in Washington Mr Trump sat at a table with Christine Lagarde, the head of the International Monetary Fund, Emir Sheikh Tamim bin Hamad Al Thani and New England Patriots owner and businessman Robert Kraft.
Following Mr Trump’s tweets last night Mrs May reiterated a statement she made earlier in the day saying she had ‘full faith’ in Sir Kim.
A Government spokesman said: ‘We have made clear to the US how unfortunate this leak is. The selective extracts leaked do not reflect the closeness of, and the esteem in which we hold, the relationship.
‘At the same time we have also underlined the importance of Ambassadors being able to provide honest, unvarnished assessments of the politics in their country.
‘Sir Kim Darroch continues to have the Prime Minister’s full support.
‘The UK has a special and enduring relationship with the US based on our long history and commitment to shared values and that will continue to be the case.’
Tory former foreign secretary Lord Hague told the BBC: ‘You can’t change an ambassador at the demand of a host country.
‘It is their job to give an honest assessment of what is happening in that country.’

Trump gave Sir Kim Darroch the back of his hand in a pair of tweets that also lashed out at outgoing Prime Minister Theresa May
One of Sir Kim’s predecessors today labelled the US President ‘insecure’ over his handling of the row.
Sir Christopher Meyer, who was in Washington from 1997 to 2003, told BBC Radio 4’s Today programme: ‘It just shows President Trump’s sensitivity.
‘His insecurity, which Sir Kim himself bore witness to.’
Referring to whoever leaked diplomatic cables from Sir Kim, Sir Christopher said: ‘Here there is a possible range of villains who come into the frame.
‘But, it was clearly somebody who set out, deliberately, to sabotage Sir Kim’s ambassadorship, to make his position untenable, and to have him replaced by somebody more congenial to the leaker.’
However, one Tory Brexiteer told MailOnline on Monday that he agreed with the President and said Sir Kim would be ‘following Mrs May out the door’.
‘Theresa May has made an absolute mess of Brexit. There is no two ways about that,’ the MP said.
‘But everybody knows as well that the ambassador will be following her out the door because people are already talking about who will replace him.
‘He has got it spot on. It’s a pity we didn’t have him doing the negotiations for us with Brussels.’
British officials are investigating whether a hostile state such as Russia was behind the leak of secret diplomatic memos in which Sir Kim said Mr Trump’s administration was ‘dysfunctional’.
The Cabinet Office is leading the inquiry amid fears that the culprit could be someone intent on damaging Britain’s relations with the US.
One Whitehall source told the Mail: ‘Someone meticulously went through the cables and picked out the ones designed to cause maximum embarrassment and harm.’
A second Government source thought it looked like something ‘out of Russia’s playbook’.
Britain’s trade minister said Monday that he would apologize to Ivanka Trump for the leak, in which Sir Kim described the administration as ‘dysfunctional’ and ‘inept.’

Off to work: Ivanka Trump was meeting Britain’s trade minister Monday after the country’s ambassador to Washington D.C. was revealed to have told senior members of the British government that her father’s presidency was ‘inept’ and ‘dysfunctional’
The emergence of the Darroch memos triggered a furious response from Mr Trump and triggered demands on the British side to find out who had leaked the documents.
Dr Fox, who is on a visit to Washington, told the BBC he would apologize to the president’s daughter, whom he is due to meet during his trip. Ivanka Trump is also a senior adviser to her father at the White House.
‘I will be apologizing for the fact that either our civil service or elements of our political class have not lived up to the expectations that either we have or the United States has about their behavior, which in this particular case has lapsed in a most extraordinary and unacceptable way,’ Dr Fox said.
‘Malicious leaks of this nature … can actually lead to a damage to that relationship, which can therefore affect our wider security interest.’
Mr Trump himself attacked Sir Kim earlier on Sunday, saying after the bombshell leak that the diplomat had ‘not served the UK well.’

Mr Trump unloaded on Sir Kim, saying: ‘The ambassador has not served the UK well, I can tell you that.
”We are not big fans of that man and he has not served the UK well. So I can understand it, and I can say things about him but I won’t bother.’
Mr Trump’s aides said Sir Kim’s position was no longer ‘tenable’ and they expected him to be removed.
Sir Kim’s assessments of the Trump administration in briefing notes from 2017 to the present are likely to prove highly embarrassing for the Foreign Office.
One suggests that in order to communicate with the president ‘you need to make your points simple, even blunt’.
He also says: ‘We don’t really believe this administration is going to become substantially more normal; less dysfunctional; less unpredictable; less faction riven; less diplomatically clumsy and inept.’
Another note questioned whether the White House ‘will ever look competent’.
Following Mr Trump’s state visit to the UK in June, Sir Kim warned that although the president had been ‘dazzled’ by the pomp, his administration would remain self-interested and ‘this is still the land of America First’.

Nigel Farage (pictured last week) has called for Sir Kim Darroch to be replaced over his frank assessment of the state of the Trump White House
In one of the most recent documents, Sir Kim refers to ‘incoherent, chaotic’ US policy on Iran and questions Mr Trump’s publicly stated reason for calling off a retaliatory air strike against Tehran following the downing of an American drone.
Media reports of ‘vicious infighting and chaos’ were ‘mostly true’ despite the president’s attempts to brush them off, he said.
Referring to allegations of collusion between the Trump campaign and Russia, the memo said ‘the worst cannot be ruled out’.
Brexit Party leader Nigel Farage, whom Mr Trump said would do ‘a great job’ as Britain’s ambassador to the US, said Sir Kim was ‘totally unsuitable for the job’.
He added in a tweet that the ‘sooner he is gone the better’.
Allies of Trump told the Daily Telegraph they believed Sir Kim could ‘no longer work wit the President’. One ex-advisor said: ‘I assume he will be removed.’
A Foreign Office spokesman said: ‘The British public would expect our ambassadors to provide ministers with an honest, unvarnished assessment of the politics in their country.
‘Our team in Washington have strong relations with the White House. No doubt these will withstand such mischievous behaviour.’
