Queen Elizabeth’s official death certificate has been released citing that the late monarch died of old age.

The UK’s longest reigning monarch died at the age of 96 on September 8 at Balmoral Castle in Scotland.

The National Records of Scotland released the Queen’s official death certificate which stated that she “died of old age at 3.10pm”.

It was the same cause of death as on her husband Prince Philip’s death certificate.

Their daughter, Princess Anne was labelled as the “informant” on the document and would have notified the local registrar of her mother’s death.

She also previously revealed that she was with the Queen in her last 24 hours.

“I was fortunate to share the last 24 hours of my dearest Mother’s life,” Princess Anne’s statement read.

“It has been an honour and a privilege to accompany her on her final journeys. Witnessing the love and respect shown by so many on these journeys has been both humbling and uplifting.”

Despite all this, the death certificate also indicated that the Queen passed away before her children and great-grandchildren could reach her side.

Prince William, Prince Andrew, Prince Edward and his wife, Sophie Countess of Wessex, were on their way to the Queen about 2.39pm but they landed an hour later.

Prince Harry made his own way to Scotland on a jet from Luton, only after his grandmother died.

He landed in Aberdeen at 6.46pm, 16 minutes after the Palace made its announcement, and then arrived at Balmoral at 7.52pm, almost five hours after she died.

Controversially, royal expert Lady Colin Campbell claimed the Queen was suffering from a “relatively painless” but “invariably fatal” condition, before announcing her death 90 minutes before Buckingham Palace.

Queen Elizabeth was buried on September 19 at King George VI Memorial Chapel in St George’s Chapel.
