US President Donald Trump lashed out for a second day at Britain's ambassador to the United States on Tuesday, describing him as "wacky" and a "pompous fool", after a leak of emails critical of the American administration.

Theresa May, who defended Darroch until the end, said on Tuesday that: "He had given a lifetime of service to the United Kingdom and we owe him a huge debt of gratitude". Whilst on the campaign trail in 2016, Trump invited the then-UKIP leader to speak at one of his rallies and he tweeted shortly after his election that Farage would do a "great job" as ambassador to the US.

What to do with Darroch will be a major issue for Britain's new prime minister to address, but former British Foreign Minister William Hague said he should not be removed.

Such "malicious leaks" can harm British-U.S. relations and "our wider security interest", he warned.

"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", Sir Kim reportedly wrote.

The British government was left in a vulnerable position after Trump barred the doors for Darroch.

Trump's tweet dealt a likely fatal blow to Darroch's strenuous efforts over two years to manage the almost-impossible task of forging stable ties with Trump's tumultuous White House.

President Trump responded by calling him "wacky" and a "very stupid guy", saying he would no longer work with the diplomat.

Foreign Office minister Sir Alan Duncan, whose brief includes the United States, said he was "severely disappointed that Boris Johnson appears unwilling to stand up for our ambassador to the USA, our PM or our country".

Sir Kim Darroch has come under fire after some of his communications with London were leaked, detailing his concern over the state of Trump's administration.

"We will continue to deal with all accredited individuals until we get any further guidance from the White House or the president, which we will of course abide by the president's direction", said spokesperson Morgan Ortagus. "A disaster! I don't know the Ambassador but have been told he is a pompous fool", tweeted the president, before concluding by thanking himself for the current state of the American economy and military. However, an investigation is underway to locate the source of the leak, which has caused great embarrassment for the British government.

Trump said he gave direction to May on how to handle Brexit, the movement to leave the European Union, but she bungled it.

"Over the last few hard days, you have behaved as you have always behaved over a long and distinguished career, with dignity, professionalism and class".

"Whenever I visited Washington as foreign secretary, I was struck by Sir Kim's professionalism and intellect", Hunt said in a statement.

The head of the diplomatic service, Sir Simon McDonald, is scheduled to appear before MPs on Wednesday, when he will give evidence to the Foreign Affairs Committee regarding the leaked emails from Sir Kim.
