Some 32 Scottish councils and 21 Welsh councils will hold all-out elections. Four English district councils and two unitary councils who normally elected by thirds will hold all-out elections because of ward boundary changes.
A third of seats are being contested in 36 English metropolitan boroughs - including Birmingham, Liverpool, Newcastle-upon-Tyne and Manchester - 63 district councils and 16 unitary authorities. Seven other English district councils will elect by halves.

Size of majority: The number of MPs that one party has over and above all others combined. Where 650 seats are contested, if a party wins 326 seats that would leave all others with 324 added together. That would give the winning party a majority of two, the smallest possible.

West Lothian Question: Shorthand term coined to describe a question posed by Tam Dalyell, once Labour MP for West Lothian.
