Mr. Trump was flying to Paris on Friday for a series of events marking the centenary anniversary of the end of World War One. The president was said to have received a phone call from Mrs. May to congratulate him on the results of the midterm elections. But the Prime Minister was reportedly met with a furious tirade, saying Mrs. May had not done enough to curb Iran.
The Washington Post told how the president also questioned her approach to Brexit negotiations and ranted about how US-Europe trade deals were stacked in the EU’s favour.
According to the newspaper, US and UK aides briefed on the conversation between the two leaders said Mrs. May was stunned by the tone of the president's call.
Downing Street is yet to comment on the report.
Washington Post journalist Rosalind Helderman said on Twitter this morning: “In AF1 call, Theresa May tried to flatter Trump with congratulations for GOP wins in the midterms. He responded by berating the British PM do badly it left her and staff shaken.
“Trump spent his days in Paris sour and sulking. After declining to drive to WW1 ceremony and snarl traffic, he blamed staff for failing to anticipate PR disaster.”
During his visit, the leader reportedly took a swipe at French President Emmanuel Macron during his 48-hour visit to the country.
He attacked Mr. Macron over his stance on Iran and also a public rebuking of nationalism.
Mr. Macron took a major swipe at Mr. Trump's "America First" policies on Sunday while delivering his speech at the Arc de Triomphe on Remembrance Day.
The French president said: “By saying ‘our interests first. Who cares about the others?’, we erase what nation holds dearest, what gives it life, what makes it great, and what is essential: its moral values."

The clash between Mr. Trump and Mrs. May is not the first, with her very first meeting with the president - shortly after he wonthe election - said to be “lacking chemistry”.
On Mr. Trump’s official visit to the UK this summer, the president also embarrassed Mr.s May by attacking her approach to Brexit negotiations.
In an interview conducted in July, the president claimed he would have done the Brexit negotiations “much differently” and claimed the Prime Minister did not listen to his advice.
But in a joint press conference with the Prime Minister following their meeting at Chequers, the US President said: "I didn't criticise the Prime Minister, I've a lot of respect for the Prime Minister.
"Unfortunately, there was a story that was done which was generally fine but it didn't put in what I said about the Prime Minister and I said a tremendous thing.
"It's called fake news."
