I've avoided posting on these threads so far but I'll bite now.
Tbh I'm quite shocked at all the vitriol about MM.
There's so much speculation about everything that's happened and the only thing to be certain of is that we probably don't know the half of it.
What we do know, is that aside from her mother, her family have behaved appallingly since news of the relationship broke.
I'm damn sure if there had been an AIBU on "should I invite my estranged family to the wedding when they've been selling stories about me" the result would have been a resounding no.
As for her father, it's no secret their relationship was not especially close and hadn't been so for some time. We don't know why though.
I personally don't think TM had any intention of going to the wedding and frankly could well be a damn site more media (and financially) savvy than people realise.
As for MM - well she can't do right for doing wrong can she?
She may have wanted her mother to walk her down the isle but DR was nervous about it? Who knows.
As it is DR will be in the car taking her to Windsor - so hardly sidelined, but playing an important and very visible role.
I liked the statement from KP - notice not "giving away" but "accompanying down the aisle".
I think it's a good move frankly and restores a bit of dignity back to the occasion.
Yes she could have done it alone, but with so many watching I'd appreciate a bit of support, especially from someone so experienced and it focuses attention back to the royal family and not the missing errant father.
It's a good PR move imho. The RF showing solidarity for MM and doing what they do i.e. put on a good show.
