Sansovino
Sorry, but I thought she was a silly woman, and nearly as annoying as Princess Margaret. Still, she didn't deserve to die in a car crash.
Sorry Sansovino, but you cannot possibly compare Diana to Margaret. Margaret was a prize winning nasty piece of work and an insufferable snob. She treated staff and those she deemed beneath her in the most appalling fashion. Even the usually sycophantic and royalist press struggled to say anything nice about her. Her life was completely vacuous, filled with shallow people, booze and parties. In short, she was horrid with no apparent redeeming features.
Diana, on the other hand, successfully achieved the banning of landmines which is one of the most corrupt, pernicious and vile "industries" on the planet and killed thousands of innocent children every year. It also made billions for the manufacturers and governments worldwide. She was courageous in the extreme to take on this cabal of big boys and they undoubtedly wished she could be silenced, but she didn't give up.
She also gave enormous support to homeless people, often away from the cameras and behind the scenes. She helped a lot of people turn their lives around.
She was involved in many other charities to which she offered unerring support for which she will rightly be remembered.
Finally, the majority of people who met her found her charming and humble. She was very far from a privileged snob and treated her staff with respect and kindness.
No matter what your thoughts on her (and of course she was absolutely not perfect), there is no comparison on any level between her and Margaret.
