Prince Charles may have Camilla Parker Bowles in his mind when he proposed to Princess Diana several years ago.

In a 1993 article for Vanity Fair, biographer Anthony Holden talked about the royal couple’s engagement and said that it actually took place at Camilla’s marital home.

“The unmarried Charles was known to be very close to two married women: Camilla and Lady (Dale) Tyron – who marketed some of her fashion designs under the label Kanga, the nickname Charles gave her. They were even said at the time to have formed a committee to set virgins fit to marry the Prince and put Diana at the top of the list… Where, after all, did Charles propose to Diana?” Holden wrote.

The royal biographer revealed that Prince Charles asked for Princess Diana’s hand in marriage while standing beside a cabbage patch in the Parker-Bowles’ back garden. But until today, Holden’s claims remain unconfirmed.

In the past, other stories have claimed that the future King proposed to the Princess of Wales at the nursery at Windsor Castle. Other sources said that the proposal took place over dinner in Prince Charles’ apartment at the Buckingham Palace.

Meanwhile, royal expert Tina Brown seems to be in agreement with Holden because she revealed that Camilla was the one who persuaded Prince Charles to propose to Princess Diana.

“His family wanted it, the public wanted it, like the last Prince of Wales, he liked to confide in married women, and his two favorites, Lady Tyron and Camilla Parker Bowles, wanted it. They had met the blushing little Spencer girl and deduced she was not going to give them any trouble… Better her than another fiery number like Anna Wallace,” she said.

According to the royal expert, Prince Charles was already feeling exhausted at that time so he decided to propose to Princess Diana. The couple tied the knot in 1981, and they were blessed with two children together.
