With the greatest of respect Anna, "subject the kids" to what? Is the King going to lock them away in the Tower of London?
Really?
Speaking more seriously, I think it is safe to say that when meeting the children, both the King and Queen would behave with maturity and put aside any ill feeling for Archie and Lili's sake, and hopefully PH would do that too. As MM has nothing further to gain by returning to the UK, she doesn't want to come back, and to be fair, she's not welcome here either -
not because of her ethnicity, as she has tried (and failed) to make everyone believe, but because of her behaviour and treatment of the BRF and the people of the UK. She clearly has no liking or respect for either, and we feel the same about her. Simples!
There's no reason therefore why PH can't bring the children by himself; it's clear that the children are often in a situation where one or both of their parents are absent, so (sad as it sounds) they have probably got used to it.
My gut feeling is that PH
wants to bring the children to the UK, but something - or someone - won't let him, and it's not because of concerns about security (there wouldn't be any).
Regarding the children's ethnicity, let's not forget that their British ancestry, as the children of the son of the King, is also a great gift to them. It takes nothing away from their Nigerian ancestry, and if they are given the chance, they can be rightly proud of
both of their ancestral countries.
So rather than focusing on just one, why not celebrate both?
