This was confirmed by The Royal Family’s verified Twitter handle.
“The Queen died peacefully at Balmoral this afternoon.
“The King and The Queen Consort will remain at Balmoral this evening and will return to London tomorrow,” a terse tweet read.
Queen Elizabeth II is the UK’s longest-serving monarch after reigning for 70 years.
Her family gathered at her Scottish estate after concerns grew about her health earlier on Thursday.
The Queen came to the throne in 1952 and witnessed enormous social change.
With her death, her eldest son Charles, the former Prince of Wales, will lead the country in mourning as the new King and head of state for 14 Commonwealth realms.
At Buckingham Palace in London, crowds awaiting updates on the Queen’s condition began crying as they heard of her death. The Union flag on top of the palace was lowered to half-mast at 18:30 BST.
The Queen was born Elizabeth Alexandra Mary Windsor, in Mayfair, London, on 21 April 1926.
