It is one of his grandmother’s greatest legacies, the Commonwealth family of nations that has grown under her reign into her pride and joy.
So when the Duke of Sussex visits Angola later this month he will have quite the task on his hands, as he attempts to cement Britain’s relationship with a country on the cusp of joining.
Angola, one of the four countries the Duke will visit as part of his tour in Africa with his wife and baby son, has indicated it hopes to become the 54th country in the Commonwealth, and the first newcomer in a decade.
The British government, which has arranged the tour via the Foreign Office, has suggested it would warmly welcome its inclusion, with those planning the tour considering the attentions of the Royal Family a way of “demonstrating the attraction of that new network of partners”.
The Duke, who has been appointed as a Commonwealth Youth Ambassador by the Queen, has already spoken of his ambition to work with the young people of the organisation, so far delivering speeches praising their energy and talents and appearing at a series of lively engagements.
His trip to Angola, which he will undertake without the Duchess as she remains in South Africa with Archie Mountbatten-Windsor, will see him tasked with rising to a more senior diplomatic challenge.
