In this part of the world at least, the coronation is unlikely to attract the same attention as in earlier times.
For example, 85 years ago, my grandmother invested what for her would have been a year’s wages in a radio set. She did that solely because she wanted to “listen to the coronation” (ie. of King George VI).
Cannot imagine this coronation generating anywhere near that level of interest!
There are a number of reasons for that - not just the unpopularity of Charles III. At the forefront would be declining British influence in this part of the world, paralleling Britain’s post-WWII decline as a world power. The clinchers would have been two events which happened almost at the same time - Britain’s withdrawal “East of Suez” and its entry into the Common Market. Upon entry into the EEC, Britain thereby abandoned trade with the Commonwealth.
Ever since, the term “Commonwealth” has meant very little, apart from that biannual Talk Fest called the “Commonwealth Heads of Government Meeting”. Commonly referred to by its acronym CHOGM, it would more accurately be described as “NATO” - ie. “No Action, Talk Only”
