@MissBarbary -
No. AWS is an awful idea.
At the moment at Westminster Conservatives have 40% women ; Labour 47% ; SNP 7% and Liberal Democrats 3% so AWS isn't even making that much of a difference.
Sorry but on the numbers you're wrong, by a long way.
commonslibrary.parliament.uk/general-election-2019-how-many-women-were-elected/
"Of the current 220 women MPs, 87 are Conservative (24% of all Conservative MPs, up from 21% in 2017). 104 are Labour (51%, up from 45% in 2017), 16 are SNP (33%, down from 34% in 2017) and seven are Liberal Democrat (64%, up from 33% in 2017). There are also six female MPs amongst other party groups."
The proportion of Labour MPs that are women is OVER TWICE that of the Conservatives. I do have some reservations about AWS but it's undeniable that in increases women's representation.
The lib dem number is interesting, but if I remember rightly prior to 2017 they had NO female MPs at all. Would be interested to find out more about what they've done (if anything) to change that, but with so few MPs in total it may be a random by-product of small sample size.
