"Prince Harry is attempting to drum up interest in a follow-up to Spare as he faces the prospect of a staggering legal bill from his latest courtroom defeat, award-winning journalist Paula Froelich tells News24.com.au."
You could be right about the polls, and many don't trust them though they seem to be consistent.
The mistake The Palace made imo was to try and trash Diana shortly after her marriage to Chuck, and sanitise Camilla who consistently remains low in the same polls year after year despite a ruthless campaign and millions of pounds in PR by b'stard Bolland. Chuck coldy pushed ahead with what he wanted, and the fiction that he's soft and kindly is a joke.
Fault on both sides, but people still don't like how she was treated. This is reflected in comments. Catherine and William are likened to Diana. The Ho trying to be Diana, channel Diana, the Tapes corrupted. There's a reason for this.
I used to be ambivalent about her, but the more I've learned the worse it seems, and it's only thanks to the Internet. They never let her know the Bashir bank statements were fake though they knew, and let her stew in fear she was being spied on and laughed at her paranoia. Shauna Kay makes the point that Cam wasn't monitored, but MI5 and BP were always looking for dirt on Diana. No matter how long she's been dead, wicked is wicked and is not erased by the passing years.
