As the day nears, ask yourself a question. What is this weekend’s coronation for? It will not make Charles III the king. He is that already. He became king when his mother died last year, and after a smoothly performed and sensibly low-key accession process. The line of succession is also firmly set.
Nor will the coronation make any difference to the king’s ability to carry out his constitutional role as Britain’s head of state. It will confer no new power on him. He already gives his assent to laws.
