Labour candidates won five out of the seven combined authority (metro-)mayor elections in May 2021, with the Conservative candidates winning the remaining two. Labour mayors now govern combined authorities covering more than 8.5 million people and Conservative mayors govern areas covering more than 3.6 million people. The Green Party came third in all five elections they contested, ahead of the Liberal Democrats.
In three elections, the winning candidate won more than 50% of the first preference votes. The other elections went to the second preference votes round.
Tracy Brabin was elected mayor of West Yorkshire, the first woman to hold a metro-mayor position.
