The Queen's husband was admitted to a London hospital on Feb. 17 after feeling unwell.

He spent a month in hospital and was released on March 16, when he returned to Windsor Castle.

His illness was said to not be related to COVID-19, the Queen and Philip were vaccinated against the coronavirus in early January.

Philip retired from public duties in 2017 and had rarely appeared in public since.

Philip married the then-Princess Elizabeth in 1947 and was the longest-serving royal consort in British history.

He and the Queen had four children, eight grandchildren and nine great-grandchildren.

A former naval officer and keen polo player, Philip enjoyed robust health well into old age but he had a number of health issues in recent years.
