Only because accuracy is conducive to productive debate:
Rachel Reeves (something of a bête noire for the Corbynites, for reasons I won't pretend to understand), current something-or-other in the shadow cabinet wrote a book called Women Of Westminster: The MPs Who Changed Politics. Which as you might expect, contains quite a lot about Nancy Astor, the first female MP to take her seat in the House of Commons. I've not read it, so offer no opinion on whether it's a balanced picture, including the Nazi stuff or a fawning hagiography.
NB - Astor was the first woman to take her seat, Constance Markievicz was elected for Sinn Fein before her and didn't take her seat, per Sinn Fein policy.
As you were.
