On 2 May, 107 English councils held elections with more than 2,000 seats being contested. Some were for metropolitan boroughs such as Manchester city council and others for unitary authorities such as Bristol or Dorset. Both structures are single-tier authorities with responsibility for the whole range of council services, including education, social care, rubbish collection and parks.
There were elections for 58 district councils, lower-tier authorities whose responsibilities are more limited, but include planning, housing and recycling. District councils typically elect a third of their seats each year on a four-yearly cycle, and elect the upper tier council — usually the county council — in the fourth year.
There were elections in London for the London assembly as well as 11 mayors including those of London, greater Manchester and Liverpool. These were subject to changes in their voting system since the last time they were up for election. They are now elected on a first past the post basis. Police and crime commissioners were also up for election.
