’Palace sources’ means fuck all, it’s just something journalists say.
Mostly these are quotes from ‘royal experts’ who don’t have any insider info, they’ve just made educated guesses.
Who knows why Megan didn’t go to Scotland, but it will be some basic reason like they realised Kate wasn’t going and it would be weird.
Yes William will have invited them to join the walkabout because who else would. Maybe he texted Harry, maybe he rang him, but one or the other, obvs.
Of course the palace leak sometimes but they won’t have done in this case because there is nothing worth leaking
You can’t draw a parallel between waffle like this and Harry’s book, don’t be silly.
