Greek-born Prince Philip, the husband of Queen Elizabeth, is “OK”, Prince William said on Monday.
As reported on GCT, he was admitted to the private King Edward VII’s Hospital in central London last week after feeling unwell.
“Yes, he’s OK, they’re keeping an eye on him,” William told reporters during a visit to a vaccination centre in eastern England.
A royal source said doctors had been acting out of an abundance of caution and that Philip was in good spirits.
There has been no official update from Buckingham Palace on his condition since last week.
His eldest son Prince Charles visited him on Saturday.
