Andrew Lownie garnered widespread acclaim for his book “Entitled: The Rise and Fall of the House of York,” which exposed the moral corruption, avarice, and extravagance of the Duke and Duchess of York.

Lownie’s work, featured in the Daily Mail and the Mail on Sunday, revealed shocking insights into Prince Andrew and Sarah Ferguson’s questionable associations, including their ties to the late convicted sex offender Jeffrey Epstein.

The book’s release, coinciding closely with the unveiling of the Epstein files last year, played a role in Andrew Mountbatten-Windsor’s retreat to King Charles’s private Sandringham estate in Norfolk, while Sarah Ferguson seemingly vanished from the public eye.

As both an author and literary agent, Lownie takes pride in the success of his bestseller. Now at 64, he identifies as a monarchist and has been sharing some explosive revelations in interviews worldwide—not limited to the troubled lives of Andrew and Ferguson.

During a speaking engagement at the Oxford Literary Festival, Lownie critiqued Andrew’s late mother, who would have turned 100 this month, asserting she frequently overstepped legal boundaries in favor of Andrew, often seen as her favored child.

Lownie further stirred controversy by suggesting that the late Queen experienced senility in her later years.

‘By the end of her life, what people don’t realise, is that she was completely gaga,’ the author claimed. ‘He [Andrew] would go up there and he would bully her into doing things. So for the last few years of her life Charles actually was running the show, rather than the Queen.’

Lownie claimed that the late Queen had ‘crossed the line’ legally ‘a lot’ when she made allowances for Andrew, who was often described as her favourite child

‘By the end of her life, what people don’t realise, is that she was completely gaga,’ the author claimed

Lownie went on to discuss unsubstantiated claims that both MI6 and the Foreign Office complained about the former Prince Andrew.

He continued: ‘He was made a vice-admiral in the Navy, and that was after these allegations. She [the Queen] entertained a lot of [his associates]. President Aliyev of Azerbaijan gave her a horse and she was thrilled. She, I’m afraid, abetted this [his misbehaviour]. The whole family abetted this – they knew about it.’

Having met the Queen at a party near Buckingham Palace in her later years, I can affirm that she was certainly not ‘completely gaga’ or, indeed, even a little gaga. In fact, she spent so long making intelligent small talk with guests at the party that she rather showed me up. I wanted to leave and go home but felt I could hardly depart before our elderly monarch.

Right to the end of her magnificent life, the Queen was undertaking her duties despite being increasingly frail. As my esteemed colleague Robert Hardman recalls in his new book, Elizabeth II, she met not one but two prime ministers, Boris Johnson and his successor Liz Truss, during the final week of her life. 

Truss told Hardman: ‘She stood up to greet me. She was clearly physically not very well but we talked for about 20 minutes. She was alert.’

Lownie also discussed the late monarch’s friendship with her racing manager, the 7th Earl of Carnarvon, who was known as ‘Porchie’, thanks to his previous courtesy title of Lord Porchester.

Discussing Andrew Mountbatten-Windsor’s character with an interviewer Down Under, Lownie said: ‘He was the favourite, he was spoiled, he has a very different character to Edward and indeed to Charles, and that’s because, I think, he has a different father.

‘I think he’s the child of Lord Porchester, and Lord Porchester was like that, and so I think that it’s a genetic thing.’

Viewers of Netflix’s popular, but wildly inaccurate, drama series The Crown will already be familiar with innuendo about the Queen’s friendship with Porchie, but it’s controversial, to say the least, that Lownie should spread such rumours.

Perhaps he should stick to writing about the living rather than those who are in no position to answer back.

After her record-breaking reign and a life devoted to duty, I would say the Queen deserves far better.
