what i briefly read, it was her father, but her being hired and people pointing it out got under her skin. I did see she was banning people bringing it up, but looks like they fired her because of that, banning unrelentingly people's opinions on reddit.
She was let go from the Green Party in the UK after running for office when it turned out she hired her father a a campaign manager after he had been charged with raping and torturing a 10 year old girl (he subsequently was convicted). She then ran for the Lib Dems, and was kicked out of the party after her and her partner’s child sex fantasies were revealed on Twitter (although both her and her partner claim that the account was hacked and the posts fake, which is quite possible). Finally, a lot of people question how she lived in the same house as her father when he was raping and torturing the 10 year old and yet she claimed she knew nothing about it.
