" Patronising women is another manoeuvre, an infamous example being then British prime minister David Cameron’s ‘Calm down, dear’ to Labour MP Angela Eagle in 2011.48 In the Inter-Parliamentary Union’s (IPU) 2016 global study on sexism, violence and harassment against female politicians, one MP from a European parliament said ‘if a woman speaks loudly in parliament she is “shushed” with a finger to the lips, as one does with children. That never happens when a man speaks loudly’.49 Another noted that she is ‘constantly asked – even by male colleagues in my own party – if what I want to say is very important, if I could refrain from taking the floor.’ Some tactics are more brazen. Afghan MP Fawzia Koofi told the Guardian that male colleagues use intimidation to frighten female MPs into silence – and when that fails, ‘The leadership cuts our microphones off’.50 Highlighting the hidden gender angle of having a single person (most often a man) in charge of speaking time in parliament, one MP from a country in sub-Saharan Africa (the report only specified regions so the women could remain anonymous) told the IPU that the Speaker had pressured one of her female colleagues for sex. Following her refusal, ‘he had never again given her the floor in parliament’. It doesn’t necessarily even take a sexual snub for a Speaker to refuse women the floor: ‘During my first term in parliament, parliamentary authorities always referred to statements by men and gave priority to men when giving the floor to speakers,’ explained one MP from a country in Asia. The IPU report concluded that sexism, harassment and violence against female politicians was a ‘phenomenon that knew no boundaries and exists to different degrees in every country’. The report found that 66% of female parliamentarians were regularly subjected to misogynistic remarks from their male colleagues, ranging from the degrading (‘you would be even better in a porn movie’) to the threatening (‘she needs to be raped so that she knows what foreigners do’).
