The trio were spotted having a meeting on a balcony visible from a public park. The meeting took place at the Royal Over-Seas League near Clarence House. Photographs of the meeting were obtained by The Mail on Sunday, with the photographer pre-arranged.

Griffiths claims she was told this when the advisor invited her to lunch at the Ivy restaurant in London, where they gave her information so she could write positive stories about Harry and Meghan, including the fact they were truing to rebuild their relationship with the King.

Griffiths, who was once friends with Harry, said she was surprised when the Daily Telegraph was reportedly told that sources close to The Duke and Duchess of Sussex were unhappy that the photographs of the meeting had been taken and published in The Mail on Sunday.

It is claimed the couple’s aides put the blame for the photograph at the Palace door.

Griffiths wrote: “I was duly tipped off about the meeting, which was held at the Royal Over-Seas League near Clarence House. The attendees settled themselves on a balcony plainly visible from the public park below. The Mail on Sunday arranged for a photographer to capture the cosy but very embarrassing scene.

“In a development which speaks volumes for their integrity, ‘sources close to the Sussexes’ then briefed the Daily Telegraph that they were ‘very frustrated’ that the pictures of the Royal Over-Seas League gathering had ended up in The Mail on Sunday – suggesting, quite falsely, that the Palace was responsible for a grotesque betrayal of trust.

“Now, just six months later, the prince was impugning my integrity, while swearing that his people never leaked and that stories that ended up in my newspaper must have been obtained illegally.”

ANL always denied the claims of unlawful information gathering.
