Queen Elizabeth thought Donald Trump was "very rude", according to a new biography

In a new book entitled 'A Voyage Around The Queen' - which is being serialised in the Daily Mail newspaper - Craig Brown explains: "Over the course of her reign, Her Majesty entertained many controversial foreign leaders, including Bashar al-Assad, Robert Mugabe, Idi Amin, Donald Trump, Emperor Hirohito and Vladimir Putin.

"She may not have found their company convivial; upon their departure, she may even have voiced a discreet word of disapproval.

"A few weeks after President Trump's visit, for instance, she confided in one lunch guest that she found him 'very rude': she particularly disliked the way he couldn't stop looking over her shoulder, as though in search of others more interesting."

By contrast, the author suggested that Trump, 78, had a completely different impression of their relationship.

He said: "For his part, Donald Trump was confident he had been her favourite guest ever."

Trump previously claimed that he had "a great relationship with the Queen" during an interview with Fox News.

The billionaire businessman - who served as the 45th US President between 2017 and 2021 - said: "We were laughing and having fun. And her people said she hasn't had so much fun in 25 years.

"Then I got criticised for it because they said we were having too much fun ... I feel I know her so well and she certainly knows me very well right now, but we have a very good relationship with the United Kingdom."
