King Charles 'too busy' to see Prince Harry as Duke of Sussex snubbed by senior royals after Spare attacks

However, the King is "too busy" to see his son according to the Telegraph.

Prince William and Kate are also not expected to meet with the Duke of Sussex during his trip.

It comes as Prince Harry unleashed multiple attacks on senior members of the Royal Family in his memoir Spare.

Harry fired digs at King Charles's wife Camilla as well as the Prince and Princess of Wales.

King Charles is understood to be at Highgrove, Gloucestershire, and according to palace sources neither William and Kate nor their children are in London or Windsor as it is the school holidays.

Earlier today, Prince Harry arrived at the Royal Courts of Justice ahead of the first day of the hearing of the privacy case against Associated Newspapers (ANL).

Prince Harry is one of several high-profile individuals to bring claims against ANL for misuse of private information.

The legal proceedings begin today in a phone-tapping and privacy case involving the publisher of The Daily Mail newspaper.

The publisher has described the allegations as "preposterous smears".

ANL denies the allegations and a preliminary will consider legal arguments and a judge will decide whether it will go any further.

Prince Harry is bringing the action along with others including actresses Elizabeth Hurley and Sadie Frost, Sir Elton John and his husband, filmmaker David Furnish, and Baroness Doreen Lawrence of Clarendon OBE.

The preliminary High Court hearing is scheduled to last four days.
