It has been reported Kate Middleton found the interaction with Prince Harry and Meghan Markle at the Windsor walkabout following the Queen's death to be extremely difficult.

“There were always sort of murmurings within the media that the relationship between the Sussexes and the Cambridges had really broken down at the time,” said writer and broadcaster Esther Krakue.

“Clearly that relationship had broken down quite significantly already and obviously the walkabout was not her idea, it was her husband Prince William’s idea so she had to go along with it because it was seen as extending an olive branch,” Ms Krakue told Sky News host Caroline Di Russo.

“But I can imagine it’s quite difficult for someone to play nice publicly with people that have had no qualms in slating you and defaming your character in the way that they have done.”
