The Duke of Edinburgh has left the NHS hospital where he had heart surgery and moved back to the private King Edward VII's Hospital for continuing treatment, Buckingham Palace has said.
Prince Philip, who is 99, underwent a successful procedure for a pre-existing heart condition at London's St Bartholomew's Hospital on Wednesday.
The Palace said in a statement: "Following the Duke of Edinburgh's successful procedure at St Bartholomew's Hospital on Wednesday, His Royal Highness has been transferred to King Edward VII's Hospital this morning.
"The Duke is expected to remain in hospital for continuing treatment for a number of days."
The nation's longest-serving consort has now spent 17 nights in hospital – his longest ever stay.
He was initially admitted to King Edward VII's in central London on 16 February after feeling unwell at Windsor Castle, before being moved by ambulance to St Bartholomew's on Monday.
At the start of the year, he gave his approval to a motto adopted by HMS Magpie, one of the Royal Navy's smallest ships.
In 2020, Prince Philip handed over his role as Colonel-in-Chief of The Rifles to the Duchess of Cornwall during a rare public appearance.
