Elected local mayors

In some areas of England voters elect a mayor.

Mayors are elected using the Supplementary Vote system. You make a first and second choice when you vote.

If no candidate gets more than 50% of the first choice votes, all except the top 2 candidates are eliminated. If your first choice candidate is eliminated, and your second choice is for one of the top 2, then your second choice is counted.
