Camilla, Queen Consort is pulling for Prince Harry and Meghan Markle to attend King Charles III's coronation. ET royal expert Katie Nicholl explained why the Queen Consort wants the couple to attend, and why she thinks their attendance could put an end to the ongoing tension amongst the royal family.«There is still that issue of the familial rift, that rupture at the heart of the House of Windsor, and of course, a lot of people are wondering if Harry and Megan and their family will come over for the coronation and whether that will finally signal some thawing of the rift that people had hoped might have taken place over the Queen's funeral,» Nicholls explained, alluding to the rift between Harry and his father, as well as with his brother, Prince William.While Nicholl added that Camilla is «very keen» for the Duke and Duchess of Sussex to attend, she said that decision will ultimately be up to them.«It's going to be a decision for Harry and Megan to make,» she said.
