Britain's longest-reigning monarch died yesterday at the age of 96.
It was announced by Buckingham Palace that Queen Elizabeth II died "peacefully at Balmoral". In a statement, the 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.”
It means that His Majesty King Charles III is the new monarch and head of state for the UK and the Commonwealth nations. Over the coming days, he will likely be closely involved in planning the Queen's funeral alongside other mourning events.
