Buckingham Palace has released a statement to say Queen Elizabeth II has died.

Buckingham Palace announced her death in a short statement, triggering 10 days of national mourning and an outpouring of tributes to her long life and record-breaking reign.

A statement from Buckingham Palace said, “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.”

The eldest of her four children, Charles, Prince of Wales, who at 73 is the oldest heir apparent in British history, becomes king immediately.

The queen’s death came after the palace announced on Thursday that doctors were “concerned” for her health and recommended she stayed under medical supervision.
