Fiona Jones, a former Labour MP, said last year that a senior Labour party politician, currently a cabinet minister, tried to seduce her by making her an age-old offer: “Do you know what I can do for you?”

Fiona Jones lost her seat in the 2001 general election. She has threatened to “blow the lid off New Labour’s female-friendly image and tell all about the astonishing sex-for-jobs culture in the Commons”.

So a former Labour party MP publicly claimed that a cabinet minister offered her promotion in return for sex. How many quietly accepted the proposition and in return were rewarded with promotion?
