It's true that not until the Parliamentary Reform Act of 1867 did skilled working men with an income of at least ten pounds a year get the right to vote. Before that it was only professional men and the nobility that could vote. You still had to be a man though.
The Ballot Act in the 1870's meant that it was a secret ballot and nobody had the right to pressure tenant farmers to vote for a particular candidate who was often their landlord. They couldn't therefore be thrown off their land for not voting for him which was the kind of corruption that happened before. This meant farmers could now vote freely. It was a gradual process and yet still not all men could vote, but of those who could, they did have to be men. They couldn't be skilled seamstresses or women farmers.
