How did MPs vote on the gay marriage bill?

How did MPs vote on the second reading of the gay marriage bill? Here, the four maps show how all MPs voted, and how each of the three main parties voted.

 

This bill would only affect England and Wales but MPs from across the United Kingdom voted. MPs that abstained (technically, voted both yes and no) are not shown and neither are those that cast no vote at all.
