A former Minister of Justice, Rachida Dati has never been far from controversy. She's made a career of challenging the comfortable ways of the French establishment; she rails against what she considers to be French anti-Muslim discrimination and blames it, in part, for the extremism behind the French terror attacks of the last two years. She's never afraid to challenge the elitism that she says restricts the lives of the poorest. Yalda Hakim talks to Rachida Dati for the BBC's 100 Women season.

Chairwoman of Santander UK, Shriti Vadera is a leading voice in British business and as shining example of what can be achieved.
