I posted the Charles article earlier in haste as I was rushing off somewhere so I've only just read it now. I really don't know what he's hoping to achieve, especially as a future extract will cover Harry's pre-wedding "meltdown", hardly something to endear him to his sons.
And how much more can there be left to say about Diana that hasn't already been said? Best to let sleeping dogs lie really.
What did surprise me was W&H saying they had very few memories of their mother, as they were teenagers (at least William was, Harry might've been 12) when she died.
