LEAKED documents detailing a 2017 meeting between then prime minister Theresa May and Donald Trump have revealed more details of the US president’s ongoing feud with Alex Salmond.

Notes taken by top US officials and seen by the Telegraph outline in detail the exchange between the two world leaders which happened in Washington DC on January 27, 2017.

Trump is quoted as asking about what would happen to Northern Ireland after Brexit, given the critical role the issue played in the negotiations.

He said: “What about Northern Ireland?

“There’s such hatred there. I just don’t understand where it comes from."

However, before May could enlighten the president as to the Irish border situation, he quickly jumped to Scotland and began attacking Salmond.

Trump reportedly labelled the former First Minister a “loser”.

The attack likely came as a result of the long-running feud between the two men and despite the fact Salmond had resigned over two years prior.

While Salmond was still First Minister the two clashed on multiple occasions over the building of a wind farm off the coast of Aberdeen, and within sight of one of Trump’s golf courses.

In a series of 16 letters to Salmond, Trump wrote: “With the reckless installation of these monsters [the wind turbines], you will single-handedly have done more damage to Scotland than virtually any event in Scottish history!”

Salmond reportedly replied just once.

The issue was finally resolved in the Scottish Government’s favour in the UK Supreme Court in 2015.

Vattenfall said their wind farm would produce the equivalent of 70% of Aberdeen’s domestic electricity demand, preventing more than 130,000 metric tons of carbon emissions.

Salmond later told Good Morning Britain: “He [Trump] went to court three times in order to delay it [the wind farm] and lost three times.

“I probably didn’t help things by texting him: ‘Once, twice, three times a loser’.

“So I got one of these two-in-the-morning tirades about being a has-been and a nobody, and that was before I lost my seat!”

Trump's tone in the meetings with May was described by those there as "bullying" and "mansplaining".

He reportedly ignored agreed topics of discussion and went on long monologues of up to 20 minutes which left May "bemused and "exasperated". 

The leaked notes also detail meetings held between the current Prime Minister, Boris Johnson, as US diplomats when he was still foreign secretary.

At a meeting with the US ambassador to the UK, Woody Johnson, on August 29, 2017, Johnson reportedly said: “We were initially anxious about the US foreign policy but Trump has been doing fantastic stuff on Syria, North Korea, China, Afghanistan.

“America is back under Trump.”

The Prime Minister added: “The president is making America great again.”

Johnson was one of the first UK figures to meet with Trump’s team after the businessman’s election victory.

He flew to the US in January 2017 and met with key Trump aides in Trump Tower, although he had been banned from meeting the president himself.

May’s top aides were reportedly suspicious of Johnson, and wanted the then prime minister to be the first to meet the newly-elected president.

A Downing Street spokesperson said: “The Prime Minister is committed to the extremely important relationship between the UK and US and to enhancing the work we do together to ensure the prosperity and security of our citizens.”
