All 129 seats are up for election in the Scottish Parliament.

The largest party is currently the Scottish National Party led by John Swinney.

The last election was in 2021 when the SNP fell one seat short of a majority.

There are 73 constituencies and each elect one MSP. This is done by a first-past-the-post system of voting where the candidate with the most votes wins.

The other 56 MSPs are elected to represent one of eight regions. Each region elects seven members using a form of proportional representation.

There have been boundary changes for this election so some constituencies have changed name and shape.

The Welsh Parliament is expanding from 60 to 96 seats and a new electoral system is being introduced.

The boundaries are changing here too. The old constituencies and regions are being replaced with 16 new constituencies that will each elect six members using a system of proportional representation.

Labour held half of the seats after the last election in 2021.

There are more than 5,000 councillors up for election across 136 councils on 7 May.

They are standing for a mixture of district, metropolitan, unitary and county councils.

Elections are also taking place in all London boroughs.

Outside the capital there are elections in the West Midlands, the North West, as well as other areas scattered across England.

There are also six county council elections, three in East Anglia and three in the South East.

Labour are defending the most seats with more than 2,500, the Conservatives over 1,300 and the Lib Dems just under 700.

Most of the seats were last contested in 2022 at a time when Reform UK stood in very few areas.

There are also six council mayors up for election, five in London and one in Watford.
