BREAKING: Britain's Prince Philip, the Duke of Edinburgh, has died

The Duke of Edinburgh - Prince Philip - has died, Buckingham Palace has said.

A statement from Buckingham Palace stated:

"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 Duke was married to Queen Elizabeth II for more than 70 years and became the longest-serving consort in British history.

It was not until May 2017, after carrying out more than 20,000 solo public engagements, that the 96-year-old retired from his own programme of royal duties, occasionally stepping out to support the Queen for big events.

Prince Philip of Greece and Denmark was born on the island of Corfu in 1921.

At the age of 18, the prince joined the Royal Navy as a cadet.

He saw active service during the Second World War, serving in the Indian Ocean and the Mediterranean, and was mentioned in despatches for his bravery.

In 1947 he renounced his Greek and Danish royal titles, took on the surname of Mountbatten and became a naturalised British subject ahead of his marriage to Princess Elizabeth.

Their wedding was the first great state occasion after the end of the Second World War.

His commitment to the Queen was unfaltering. He gave up his career in the Navy in order to support her in her role as monarch.

The Queen has described Prince Philip as her "constant strength and stay".

They had four children - Charles, Anne, Andrew and Edward.

He saw himself as a moderniser within the British monarchy, orchestrating the first royal walkabout - but he was also known for his forthright views and off-the-cuff remarks.
