Thanks again @BasiliskStare.
Bringing my comment from the other thread across here, as you've suggested that you don't mind discussing the excerpts here (as long as the discusson is text-based and doesn't veer off into the general arguments that are happening elsewhere).
The DM are clearly going to serialise the most sensational parts. However, from my perspective, assuming that what they have printed is contained in the book as printed, he has lost considerable credibility on 3 counts:
1 Highly unlikely comment attributed to KC3
2 Father wanted to marry Elizabeth but 'warned off' by Mountbatten - dates don't add up
3 Diana deciding to divorce because Charles 'in love with valet' - they had been living separately for years before the Queen told them to divorce, so how would she even know, assuming this were true? He's clearly just decided to drag up an old story.
I think, rather than this being a tribute to Diana or speaking about Diana in an 'openly positive way' as he claimed in the pre-publication interview, he is using it to score points.
