The Commonwealth has secretly begun considering who might succeed Queen Elizabeth II as its Head.
The issue is hugely sensitive because the role is not hereditary and will not pass automatically to Charles, the Prince of Wales on the Queen’s death.
The Commonwealth has set up a “high level group” to look at the way the international organisation is governed.
This group is meeting later, officially to review how the commonwealth is run by its secretariat and governors.
However, senior sources added that the gathering in London would also consider what happens when the Queen, who turns 92 in April, dies.
The group is expected to report to the Commonwealth Heads of Government Meeting (CHOGM) in London in April, which is likely to be the last that the 91-year-old Monarch will attend.
The Queen was proclaimed Head of the Commonwealth at her coronation in 1953, when she was head of state in seven of its eight members.
Although the Queen took over from her father George VI, it is not an hereditary position that will pass automatically to her son – who will be head of state in only 15 of the 53 member nations that now make up the Commonwealth.Please subscribe to our newsletter
