I think it’s like other people have noted. The BRF is doing damage control with Megs because after her regional tour of the UK and the Commonwealth stuff, she isn’t able to function as a proper member of the BRF.
Megs did all of those engagements with Harry, and she still doesn’t know how to conduct herself properly as a member of the BRF.
So the pressure will be on Megs to get it right next Thursday (the 14th).
If she fucks up WHILE IN THE PRESENCE OF THE QUEEN, then Fleet Street will not forget it.
The British royal family will not forget it.
And the British public will not forget it.
The pressure is on Meghan for these engagements, not the Queen or anyone else.
