I was reading a review of 'Ma'am darling' the other day, and it said that Princess Margaret was born into an age of deference but died in an age of egalitarianism.
I read Ma'am Darling and would really recommend it. It makes the point that for minor royals like PM, it's all downhill - born a prince/ss, then gradually becoming less relevant and newsworthy as the distance widens between them and the throne. PM was furious over the Morton Diana book and turned against Diana because of it, but she'd been happy to talk to a biographer herself a few years earlier. I had to wonder if she was annoyed because there was much less fuss over her book due to her not being young and hot anymore!
And yes, the goalposts have moved to the other end of the pitch during the Queen's reign, with the turning point being the 1960s.
However I don’t know if anyone was prepared for or expected the enormous interest in Diana and how in the ‘80s what we all wanted from her.
According to DM, everyone confidently expected the press interest in Diana to tail off after the wedding, when she'd be just another royal...
