I think it could have been to do with making a stand re. Andrew. Wills got a huge amount of criticism for being seen with him at something or other a few months back, I don’t think it’s beyond the realms of possibility he doesn’t want to incur that again. Or give Andrew notions of “a way back” now that KC and KM are out of action and senior RF members are thin on the ground. He says, “It’s him or me, Pa”, KC says, “Wind your neck in, it’s up to the Greeks who’s invited and I’m not pulling rank on a grieving family”, and PW makes a stand. Not beyond the realms of possibility.
So I think it’s either that, something kid-related, or a upcoming PR issue. Isn’t judgment due tomorrow re. one of Harry’s court cases? The one about the security assessments?
