Donald Trump and British Prime Minister Theresa May hosted a dinner with top business leaders when the US president visited the UK in July.

According to one attendee, Brent Hoberman, Trump made weird remarks about guests' pedigrees in a speech during the dinner.

Trump apparently complimented guests on their "amazing DNA" and "great bloodlines."

Hoberman spoke to Business Insider after being named in the UK Tech 100, a ranking of the 100 coolest people in the UK tech industry.

US President Donald Trump made some unusual remarks about top business leaders in a dinner speech during his trip to Britain in July, a tech investor who attended the gathering has told Business Insider.

Trump's travel schedule mostly avoided London, but included a formal black-tie dinner with around 150 business leaders, senior members of the government, and Prime Minister Theresa May. It took place on July 12 at Blenheim Palace, a 239-year-old country mansion in Oxfordshire and the birthplace of Winston Churchill.

Some invited business figures registered their disapproval by boycotting the event. Lastminute.com founder Martha Lane Fox publicly turned down the invitation with the comment: "I understand why the government have to entertain Trump but I certainly don’t want to."

But Lane Fox's Lastminute.com business partner and famed tech investor, Brent Hoberman, did decide to go.

Hoberman, who now runs incubator and accelerator Founders Factory, told Business Insider during an interview that Trump made some peculiar remarks when he stood up and gave a speech.

Hoberman, with a passable Trump impression, recounted: "Where he read, it was bad. His bits off the cuff...were also a bit odd. He banged on about Churchill about a hundred times because of Blenheim, that was clearly a speechwriter's device. He did have some great lines. He said: 'You've all got such good bloodlines in this room.' That was awful, that was script. 'You've all got such amazing DNA.'"

Trump has form when it comes to touting superior genetics. The president has repeatedly credited his position in life to "good genes." In a July 2016 speech, he referenced his late uncle, a nuclear physicist, saying: "Dr John Trump at M.I.T.; good genes, very good genes, OK, very smart, the Wharton School of Finance, very good, very smart."

Hoberman added: "It was weird because [Trump] was very warm actually, yet at the same time the news broke while he was speaking that he had given that interview in The Sun where he undermined Theresa May."

Trump committed a diplomatic faux pas during his visit by criticising the prime minister's approach to Brexit in an interview with the British newspaper. He told The Sun that he had advised May on "how to do Brexit" but that "she didn't listen to me." He also said ex-foreign secretary Boris Johnson would make a "great prime minister." He later appeared to walk back the remarks.

"It was utterly bizarre, and I think I saw someone whispering in Theresa May's ear," said Hoberman, suggesting that this was the moment the British prime minister was made aware of Trump's remarks in The Sun.

According to Hoberman, Trump also joked about making UK Chancellor Philip Hammond "jealous" because "I spend all my time with Theresa May." "He was trying ... but he doesn't come across as deeply analytical," Hoberman said.

A US official who also attended the dinner said it was clear the president was joking. The White House declined to comment.

While others shunned the dinner, Hoberman thinks it's better to engage

Hoberman said he had no regrets about attending the dinner. Part of the reason he went was not to meet Trump, but to meet the other guests, who included GlaxoSmithKline CEO Emma Walmsley, and BlackRock boss Larry Fink.

"I'm not a Trump advocate or apologist in any way. I think what he does is nuts," Hoberman said. "I don’t think I’m making a statement by not being there… [it doesn’t] do any good. I think by being part of the conversation and engaging and trying to understand... We talk about filter bubbles and how negative they are and how Trump plays them, not even engaging would be a circular reference. One should try and engage where one can."
