Monthly tracking of the total number of seats across Local and National Government held by Political Parties across the UK.
The data for the report is taken from the live Oscar political database.
The monthly extracts for analysis were started in April 2022.
The counts are members of political parties holding seats across all National, Devolved and Local Governments representing Constituencies, Devolved Regions and Constituencies, Electoral Divisions and Wards.
Updates to this table are made monthly and the total number of members will vary according to boundary changes, council changes, by-elections, general and local elections.
Significant events that may have a notable effect on the data (both volume of seats and political change) are highlighted in red at the top - namely local and national elections and Council changes.
The first table shows a count of members by month across each political party.
To better reflect the true picture with the fluctuating number of members/seats each month, the second table provides a percentage view of the total seats for each party each month and highlights if the proportion of seats has increased or decreased.
