Meghan Markle Will Not Attend King Charles III’s Coronation Ceremony, Citing Inauthenticity
Buckingham Palace recently said that Harry will go to the crowning ceremony at Westminster Abbey on May 6, but his wife, Meghan Markle, won’t be joining him. She’ll stay in California with their two kids, Archie and Lilibet.

Before Meghan decided not to go, Harry and Meghan had asked Buckingham Palace lots of questions about where they’d sit and what security they’d have. But after Meghan chose not to go, reports said she felt it wouldn’t be genuine to attend because of her difficult relationship with Harry’s family.
