Prince Charles has arrived at the hospital where his father the Duke of Edinburgh has been admitted.
Philip remains in King Edward VII’s hospital in London after he was admitted on Tuesday evening as a precautionary measure and walked unaided into the medical centre.
Charles was seen arriving at the hospital on Saturday afternoon.
The duke, who turns 100 on June 10, is in hospital for an undisclosed reason, although it is not coronavirus-related.
On Friday, sources told PA news agency: “Following consultation with his doctor the Duke of Edinburgh is likely to remain in hospital for observation and rest over the weekend and into next week.
“As we have said previously the doctor is acting with an abundance of caution. The Duke remains in good spirits.”
