The Duke of Edinburgh Prince Philip has left hospital this morning following a stay of a month due to heart problems.

The Queen's husband, 99, underwent heart surgery on March 3 just three months before his 100th birthday.

He left the private King Edward VII’s Hospital in central London in the back of a black BMW, having been in hospital since February 16.

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

He was initially driven to King Edward VII’s Hospital by car after feeling unwell at Windsor, but two weeks later was moved to St Bartholomew’s Hospital in the City of London by ambulance.

He had a successful procedure on a pre-existing heart condition at St Bartholomew’s on March 3, before being transferred back to King Edward’s to recuperate and to continue his treatment.

Concern has been heightened for the duke because of his advanced age.

Bradford Telegraph and Argus:

Philip has been treated for heart problems in the past and in 2011 was rushed to hospital by helicopter from Sandringham after suffering chest pains as the royal family was preparing for Christmas.

In the serious health scare, he was treated for a blocked coronary artery at Papworth Hospital in Cambridgeshire and underwent a minimally invasive procedure of coronary stenting.

St Bartholomew’s is home to Barts Heart Centre – Europe’s largest specialised cardiovascular service.

The duke was visited in King Edward VII’s Hospital on February 20 by his eldest son, the Prince of Wales, who made a 200-mile round trip and stayed for around 30 minutes.

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

The couple, who have been married for 73 years, received their first Covid-19 jabs in January.
