Prince Charles, 72, was the first Royal Family member to visit his father Prince Philip, 99, in hospital following the Duke of Edinburgh’s admission on Tuesday evening.
On Saturday, Charles left Gloucestershire and travelled to London where he paid a 40-minute visit to his father at King Edward VII’s private hospital.
Express.co.uk understands the visit was made “in exceptional circumstances” in accordance with the hospital’s COVID-19 visitor policy.
