In his first speech as King, Charles III said he would endeavour to serve his subjects, wherever they live “in the UK, the realms and territories across the world”.

But following the death of his mother, Queen Elizabeth II, several realms – countries other than the UK that have the British Monarch as head of state – say they may become republics. Barbados became a republic in 2021. Antigua, Belize, Jamaica and Grenada may follow.

King Charles III has also just become the elected head of the Commonwealth of Nations. But will any new republics leave because of its roots in Empire, or embrace an organisation that represents nearly a third of the people on Earth?

This week on the Inquiry, we ask: what’s the future of the Commonwealth under King Charles III?
