Prince Harry, Meghan Markle locked in negotiations with royal family?

Prince Harry and Meghan Markle are reportedly 'locked in negotiations' with the royal family over the terms of their attendance a King Charles III's coronation plan.

The Duke and Duchess of Sussex have not confirmed yet whether they will attend King Charles's landmark ceremony. However, the firm is reportedly preparing the coronation plan without the couple.

The California-based couple want assurances on several requests including how prominent a role they will play and that their son's birthday will be recognised during the weekend.

According to some, they also want to celebrate Archie Harrison's fourth birthday on May 6 at the palace, the same day as the Coronation. But, it is unclear whether the royal family will agree to all of the Sussexes' demands.

However, the monarchy is reportedly drawing up a version of the Coronation plan that does not include Meghan and Harry.

"Two versions of the plans [for the day] are being drawn up. One includes Harry and Meghan and one doesn’t. Timings are all approximate at this stage, but they are working towards a timetable now," an insider told the Mail.
