There are 32 million women in the UK, 51% of the population.
But the House of Commons is 71% male.
Of the 650 seats in the House of Commons 459 are occupied by men and 191 women.
Since 1918 there have only been around 450 female MPs, so there are more men at Westminster right now than there have ever been women.
In the 2015 election there were 102 seats without any women candidates and 80% of seats with only 2 or fewer women selected to stand.
At the current rate, based on the last 4 elections it will take nearly half a century to achieve a balanced Parliament of around 50:50 men and women.
Around 40 countries have proportionally more women in their parliaments than the UK, so this is not an impossible dream.
We only need 134 more women MPs from a population of 32 million women.
