Meghan Markle annoyed the Queen on her wedding day by ignoring specific royal protocol, book claims

Instead of the traditional father of the bride, Thomas Markle, handing her over to the groom, it was decided on short notice that Prince Charles would do the honours.

Thomas had decided not to come to the wedding when he became embroiled in a scandal after it was discovered by The Mail on Sunday that he had staged photographs with paparazzi for cash.
But the late Queen reportedly felt regret that the bride had not made up with her estranged father before the paparazzi drama unfolded.
According to Nicholl, the fact that Harry had not yet met Thomas and that Meghan was still not speaking to her father concerned the Queen, and while she rarely intervened, she made a point of speaking to Harry and Meghan about the situation.
‘It was the Queen’s feeling that Meghan should sort things out with her father and that Harry should have met Thomas before the wedding,’ a family friend told the author. ‘She thought the whole thing could have been better handled.’

But once the deceit of his actions around the photographs was revealed, the duchess’s relationship with her 80-year-old father broke down, and it seems they still don’t speak.
Although Meghan was not alone in choosing to forgo tradition for her wedding, as her husband-to-be Harry also wanted to carve out his own image for the big day.
