Harry and Meghan will be invited to the coronation - by necessity - but this toxic pair will be kept at a careful arm's length by all and sundry, excluded from the balcony or carriage procession, and probably positioned somewhere suitably inconspicuous. Most of the family will be wary of them, most will wherever possible avoid them and the crowds will likely boo them. There will be no lucrative photo ops with William or Kate. The Wales children will be in the limelight, but Harry and Meghan's children will be excluded, due to age.
Meanwhile, over in the States, where they no doubt expected to be feted when they planned their dramatic departure from the UK, opinion polls reveal them to be less popular now than even Prince Andrew. South Park mocked them to general acclaim and The Cut published a contemptuous piece about the possible relaunch of the Tig last week.
They've been snubbed and excluded from every big social event, from the Met Gala to Obama's birthday party and Elton John's Oscar's bash. The only parties they have attended have been those hosted by social pariahs like Ellen de Generes.
They are coming across as increasingly desperate and embarrassing. It's hard to to see any possible comeback from here.
