Prince William sought Queen’s assurance before Harry, Meghan’s wedding

Prince William sought assurances from the Queen prior to Prince Harry and Meghan Markle's wedding, according to a royal author.

Harry and Meghan, who married in May 2018, had been together for less than two years, raising concerns within the royal family about the speed of their relationship. These concerns reportedly led William to ask his grandmother for a key guarantee.

In his memoir, Spare, Harry recounted the significant tension between him and William during the wedding planning.

Additionally, in Catherine, The Princess of Wales: The Biography, author Robert Jobson claims that the brothers' relationship worsened further leading up to the 2018 wedding.

He wrote: "By the time William was confirmed as best man, the relationship had worsened. I have been told that still concerned about the match, he'd sought assurances from the Queen that Harry's bride would not be wearing any of Princess Diana's jewellery, even though his own wife was allowed to wear it. 

"Despite sharp digs and thin skins on both sides, the wedding at Windsor in May 2018 was a spectacular success. In public, the Royal Family were all smiles, though privately they were at daggers drawn."

Although Meghan did not wear any of Diana's jewellery during the wedding ceremony, she famously wore her aquamarine cocktail ring to her evening reception along with her Stella McCartney halterneck dress. 

Meghan has also worn several of Diana's pieces including a Cartier bracelet and butterfly earrings over the years.

Less than two years after their wedding, Harry and Meghan sensationally quit their royal roles and the UK for a new life in America - and their relationship with William and Kate now appears to be at rock bottom.
