Prince Harry panics as Meghan Markle refuses to be ‘absolute vault’

Prince Harry is flabbergasted as Meghan Markle speaks about their private rendezvous with King Charles.

The Duke of Sussex, who has touchdown UK this week alongside his wife and children, is upset days after Meghan spoke to Martha Stewart about her meeting with King Charles at the Highgrove House.

An insider tells Closer Online: “This is the absolute worst thing that could be happening right now. Here they are trying so hard to build back trust – Harry's giving his father and palace staff these assurances that he and Meghan will both be total vaults – and then this comes out.”

They add: “No doubt royal advisors will see the headlines about Meghan supposedly talking about her visit with His Majesty as a full-scale disaster and use it as proof that she can't be trusted.”

Martha earlier told PEOPLE: “I had dinner with Meghan Markle the other night. We were both guests at a party in California. She had just gotten back from the palace. I didn't talk to her really more than to say a couple of words, but I know she was talking about it.”
