When the world's richest man and his wife decided to divorce, the numbers were always going to be big.

And so it proved this week, when Amazon founder Jeff Bezos and his wife MacKenzie agreed the terms of their split.

MacKenzie Bezos will keep a 4% stake in the online retail giant. Her stake is worth $35.6bn (£27bn) on its own, making her the world's third-richest woman (and the 24th richest person in the world).

But who are the other women at the top of the global rich-list? And how did they get there?

The 65-year-old inherited her wealth from her mother Liliane Bettencourt, who died in September 2017 aged 94. The two had been estranged and entered into a long dispute in 2007.

Ms Bettencourt-Meyers filed a lawsuit over concerns that her mother was being exploited by members of her entourage amid declining health. But they reconciled in the years before her mother's death.

Ms Bettencourt-Meyers is also an academic and has published books on Greek gods and Jewish-Christian relations.
