Prince Philip is expected to remain in hospital for “several days” as he continues to receive treatment for an infection, Buckingham Palace has confirmed.
In a short statement, the Palace said the Duke of Edinburgh was “comfortable and responding to treatment” but “is not expected to leave hospital for several days”.
“The Duke of Edinburgh remains at King Edward VII’s Hospital where he is receiving medical attention for an infection,” it added.
Prince William, the Duke of Cambridge said his grandfather was “OK” when asked about the duke’s health during a visit to a vaccination centre in Norfolk on Monday.
And on Tuesday, the 99-year-old’s youngest son Prince Edward, the Earl of Wessex, told Sky News he was feeling “a lot better” and “looking forward” to getting out of hospital.
Philip, who is now into his eighth day in hospital, was admitted to the private King Edward VII’s Hospital in central London last Tuesday evening as a precautionary measure after feeling unwell but walked into the building unaided.
He received a visit from his eldest son, the Prince of Wales, on Saturday - a rare occurrence as the duke is known for his “no fuss” attitude.
Sources told PA news agency Philip’s doctor was “acting with an abundance of caution”.
Members of the royal family have continued with their duties since the duke was taken to hospital after telling his doctor he felt unwell.
The morning after Philip was admitted, Charles and the Duchess of Cornwall - who have received their Covid jabs - visited the Queen Elizabeth Hospital in Birmingham to learn about vaccination trials.
Last Thursday, the Queen carried out her first official in-person event of the year, making one of her most senior aides a Knight Commander of the Royal Victorian Order in a ceremony at Windsor Castle.
Philip has been spending the latest lockdown with the Queen at Windsor and in January they both received Covid vaccinations.
The duke last had a spell in hospital in December 2019, when he was treated for a "pre-existing condition" and discharged on Christmas Eve after four nights.
