Voters in England will go to the polls on 2 May to elect more than 2,600 councillors and 10 metro mayors, in the last set of local elections before the general one.

Labour and the Conservatives are defending just under 1,000 seats each, the Liberal Democrats about 400 and the Greens just over 100. Police and crime commissioners in England and Wales are also up for election.
