Britain’s Prince Philip has spent a third night in a London hospital after being admitted earlier this week for what Buckingham Palace described as “a precautionary measure.”
The palace said Philip’s admission was taken on the advice of his doctor, and that he is expected to remain there for a few days of “observation and rest.”
Philip, who retired from public duties in 2017, rarely appears in public. His most recent public event was a military ceremony at Buckingham Palace in July.
During England’s current coronavirus lockdown, the duke has been staying at Windsor Castle, west of London, with the queen, who has performed duties such as meetings with dignitaries remotely.
The royal household is planning celebrations to mark Philip’s 100th birthday on June 10, lockdown restrictions permitting.
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.
