Prince Philip had 'successful procedure' for pre-existing heart condition

Prince Philip has had a "successful procedure" for a pre-existing heart condition, Sky News reports.

Buckingham Palace said: "The Duke of Edinburgh yesterday underwent a successful procedure for a pre-existing heart condition at St Bartholomew's Hospital.

He will remain in hospital for treatment, rest and recuperation for a number of days, the statement said.

The Duke of Edinburgh, 99, is being treated at St Bartholomew's Hospital in London. 

Philip, the nation's longest-serving consort, has spent 16 nights in hospital - his longest ever stay.

He was initially admitted to the private King Edward VII's Hospital on 16 February as a precautionary measure after feeling unwell.

Four days later, he was visited by his eldest son the Prince of Wales, who made a 200-mile round trip and stayed for around 30 minutes.

The duke has spent most of lockdown residing at Windsor Castle with the Queen for their safety, alongside a reduced household of staff dubbed HMS Bubble.
