An elaborate plan for the Queen's funeral included her son, Prince Charles' official title as monarch.
As Express UK reports, fears about the Queen's deteriorating health continue to grow, especially after the leak of a detailed plan for her funeral over the weekend, which was attended by her son, Prince Charles, when he ascended the throne.
According to an official leaked briefing obtained by The Australian, all Commonwealth countries will observe ten days of mourning whenever the 96-year-old monarch passes away, with a state funeral in Australia.
The briefing also revealed that Charles would be declared King of Australia at a special meeting of the Executive Council in Australia.
Governor-General David Hurley would officially announce Charles as King at a later session of the Australian Parliament House.
As King of Australia, Prince Charles' full title would be 'Charles the Third, by the Grace of God King of Australia and his other realms and territories, Head of the Commonwealth'.
