The King has returned to his holiday home in Norfolk, ready to undergo treatment for an enlarged prostate next week.

King Charles, 75, flew back from Scotland with the Queen on Friday and was seen travelling to Sandringham.

He has spent the past week in the sanctuary of Birkhall on the Balmoral estate and got his diagnosis on Wednesday after his symptoms led to a check-up.

The King, who has cancelled engagements and been ordered to rest, will be admitted to hospital in the coming days for a corrective procedure for the benign condition.

Buckingham Palace, in an unprecedented double royal health scare, announced the news 90 minutes after Kensington Palace said the Princess of Wales was in hospital after abdominal surgery.

Queen Camilla said the King is “fine” and “looking forward to getting back to work” when she visited an art gallery in Aberdeen on Thursday.

The Queen will continue with her royal duties on Monday, visiting one of Swindon’s oldest family-run businesses – Deacon & Son Jewellers – in Wiltshire.
