Theresa May’s first Prime Minister’s Questions was widely considered a success.

She was labelled “the spitting image of Margaret Thatcher”, her attempts at jokes did not fall flat, and – most importantly - she was able to put Jeremy Corbyn in his place by boasting about the Conservative’s party’s progress with gender equality.

May used herself as proof - What does the Conservative party do for women? “It makes us Prime Minister!” – and the number of women she's promoted to top cabinet positions spoke for themselves.

But what people failed to recognise was that one of her top women was suffering from a classic example of sexism right in front of everyone’s eyes.
