Meghan Markle's absence at King Charles' Coronation raises questions.

Demonstrators gathered in Trafalgar Square to show support for Meghan Markle, who did not attend King Charles' coronation. Some held up signs featuring Meghan's face and messages such as "the people's princess," while others protested the monarchy and the coronation itself. Buckingham Palace and a spokesperson for Archewell, the organization founded by Meghan and Prince Harry, announced last month that Meghan would not attend the coronation. Harry did attend, but did not have a formal role in the ceremony.
