Meghan Markle and Prince Harry risk 'fatal, irreversible blow' to royals with Coronation decision

In a statement to GB News at the time, a spokesperson said: “I can confirm The Duke has recently received email correspondence from His Majesty's office regarding the Coronation.

"An immediate decision on whether The Duke and Duchess will attend will not be disclosed by us at this time."

As May 6 approaches, an expert has warned the royal couple that not attending could be “fatal” to their relationships with working members of the family.

PR expert and Go Up's Chief Executive Edward Coram-James warned: “In a universe in which the damage already caused by the rift is still recoverable from, at least in part, a no show would be the fatal, irreversible blow, both in the Public perception as well, potentially, as within the family itself.

"It risks drawing out the conflict over the long term."

He continued: "On the other end of the spectrum, the Sussexes not attending would draw as much, if not more, media attention.

"It would give further oxygen to the rift and allegations that the Sussexes have levelled at the Royal Family.

“And the shadow of their absence would loom large over the entire ceremony, risking becoming the elephant in the room and an unwanted side show."

The King’s Coronation also coincides with Archie’s fourth birthday, spurring rumours that the Sussexes will snub the ceremony altogether and instead celebrate the anniversary as a family.

Previously, royal expert Charles Rae said that Archie’s birthday presents the “perfect excuse” for the pair not to turn up.

He said: “Let's not forget that Meghan has a perfect excuse not to turn up.

"On the same day, it is the fourth birthday of little Archie.

"So, it may well be that she'll stay behind and enjoy the celebrations with her son."

King Charles’s Coronation will be held at Westminster Abbey.
