Look, absolutely no one vaguely objective and intelligent with any experience of life, thought of her as a saint. I was born around the same time as her and I remember!
She just happened to have a lot of good qualities like unstuffiness, good humour and a bit of warmth about her and of course she was physically attractive too, which rather showed up the RF at the time. She was actually likeable! She wasn’t, for example, too posh to hold someone’s hand without wearing gloves. She became hugely popular of that.
And we saw her transformation from shy girl to woman who was on the brink of finally taking control of her rather tempestuous, and very public life, however that would pan out.
She was the most famous woman in the world at the time, there was no Internet at the start, but she was on the front page of most papers almost every day. One photograph of her sold for thousands and thousands of pounds.
It’s only now, decades after her death, that people seem hell bent on trying to prove she wasn’t saintly, when to my knowledge, no one called her that at the time!
