Britain’s 99-year-old Prince Philip has been admitted to a London hospital after feeling unwell, Buckingham Palace said Wednesday.
The palace said the husband of Queen Elizabeth II was admitted to the private King Edward VII Hospital on Tuesday evening.
It said the admission is “a precautionary measure” on the advice of Philip’s doctor and that the senior royal is expected to remain in hospital for a few days of “observation and rest.”
His illness is not believed to be related to COVID-19. The queen and Philip received a first dose of a vaccine against the coronavirus in early January.
Philip, also known as the Duke of Edinburgh, retired from public duties in 2017 and rarely appears in public.
During England’s current coronavirus lockdown, he has been staying at Windsor Castle, west of London, with the queen.
Lockdown permitting, the royal household is planning celebrations, to mark Philip’s 100th birthday on June 10.
Philip married the then-Princess Elizabeth in 1947 and is the longest-serving royal consort in British history. He and the queen have four children, eight grandchildren, and nine great-grandchildren.
