Britain's Prince Chares visits father Philip in hospital

Charles arrived at the back of the London hospital where Philip, the 99-year-old husband of Queen Elizabeth, has spent four nights.

Philip, the Duke of Edinburgh, was admitted to hospital on Tuesday (February 16) as a precautionary measure after feeling ill with an ailment that is not related to COVID-19.

He is expected to remain in hospital until next week, a royal source said on Friday (February 19), adding that doctors were acting out of an abundance of caution and the duke remains in good spirits.

Both Philip and the 94-year-old queen received their first dose of the COVID-19 vaccine in January.
