He is said to have walked in unaided. Buckingham Palace said there was no update on the duke's condition, having previously said he was "in good spirits". His eldest son Charles made a 200-mile round-trip from his home in Highgrove, Gloucestershire, on Saturday afternoon. Charles was the first member of the royal family to visit the duke and it is understood that his visit was due to his father's extended stay.
