Re funerals and coronations - I think we are in a weird transitional time.
We have had the longest period ever between two monarch funeral / coronations.
And the most recent Coronations have been the only two to take place in the television age.
And we are in a period of time where life in general is less ceremonial and tradition bound.
Now that can go either way in terms of Royal events - they tone down to be more like the rest of the population, or they are encouraged to put on the pomp and circumstance for nostalgia and entertainment.
I think they’ll be some sort of middle ground.
Prince Phillip’s Covid funeral is not a bad starting point (just with more guests filling the whole chapel. Just one short parade within the Windsor castle grounds, military represented, family walk together. Enough room to invite representatives from all walks of life and overseas guests.
And combine the two separate ceremonies the late Queen had into one, ending in the lowering of the coffin.
Security costs will be lower than trying to police London.
