Prince Philip has left hospital after recovering from an infection and undergoing a heart procedure.

The Duke of Edinburgh, the nation’s longest-serving consort, spent 28 nights as an in-patient – his longest ever stay.

He was initially taken by car to the private King Edward VII’s Hospital in central London on February 16, after telling his doctor he felt unwell. But two weeks later was moved to St Bartholomew’s Hospital in the City of London by ambulance.

The duke underwent a successful procedure on a pre-existing heart condition at Barts on March 3, just three months before his 100th birthday, before returning to King Edward VII’s a few days later to recuperate and continue his treatment.

Philip was visited in King Edward VII’s on February 20 by the Prince of Wales, who made a 200-mile round trip from his Gloucestershire home and stayed for about 30 minutes.

Concern about the duke has been heightened because of his advanced age and his hospital stay comes amid troubled times for the royal family.

During Philip’s spell in hospital the Duke and Duchess of Sussex plunged the monarchy into a crisis by accusing a member of the royal family of racism – not the Queen or Philip – and claiming that Meghan received no support with her mental health problems.
