In 1918 the Representation of the People Act was passed which allowed women over the age of 30 who met a property qualification to vote. Although 8.5 million women met this criteria, it only represented 40 per cent of the total population of women in the UK.
The same act abolished property and other restrictions for men, and extended the vote to all men over the age of 21. Additionally, men in the armed forces could vote from the age of 19. The electorate increased from eight to 21 million, but there was still huge inequality between women and men.
