Buckingham Palace has issued a statement announcing that the Duke of Edinburgh has died.

The statement read: "It is with deep sorrow that Her Majesty The Queen has announced the death of her beloved husband, His Royal Highness The Prince Philip, Duke of Edinburgh. His Royal Highness passed away peacefully this morning at Windsor Castle."

The Royal Family announced that they will "join people around the world in mourning his loss".

Further announcements from the Royal Family will be made in due course.

Prime Minister Boris Johnson  said: "We mourn today with Her Majesty the Queen, we offer our condolences to her and all her family and we give thanks as a nation and a kingdom for the extraordinary work of Prince Philip, the Duke of Edinburgh."

He was married to Queen Elizabeth II for more than 70 years.

The duke was born on June 10 1921 on the Greek island of Corfu.

He was a prince of Greece and Denmark and his parents were Prince Andrew of Greece and Princess Alice of Battenberg.

He was exiled from Greece as a child and grew up in France, Germany and Britain.

He is known for supporting the Queen through her long reign, and carrying out thousands of royal engagements.

He also was involved for decades with hundreds of charities, and set up The Duke of Edinburgh’s Award youth adventure scheme.

Prince Philip was due to celebrate his 100th birthday on June 10, this year.

He was 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.

He died aged 99.
