Notes to editors

1. The Electoral Commission is the independent body which oversees elections and regulates political finance in the UK. We work to promote public confidence in the democratic process and ensure its integrity by:

  • enabling the delivery of free and fair elections and referendums, focusing on the needs of electors and addressing the changing environment to ensure every vote remains secure and accessible
  • regulating political finance – taking proactive steps to increase transparency, ensure compliance and pursue breaches
  • using our expertise to make and advocate for changes to our democracy, 
  • aiming to improve fairness, transparency and efficiency

The Commission was set up in 2000 and reports to the UK, Welsh and Scottish Parliaments.

Our statutory post-poll report on the 2021 Senedd election was published in September and includes details of our campaign related recommendations. 

2. Non-party campaigners must register with the Commission if they intend to spend more than £10,000 campaigning at a Senedd election during the regulated period. 

Every political party that contested the Senedd election is required to submit campaign expenditure returns to the Electoral Commission, as well as non-party campaigners who spent over the registration thresholds. The deadlines for delivering spending returns depend on how much a party or campaigner spent. 

Political parties and non-party campaigners that spent under £250,000 at the Senedd election were required to submit their returns by 6 August 2021. 

Political parties and non-party campaigners that spent over £250,000 have until 6 November 2021 to submit their audited returns.

The Commission has published the returns as they were submitted by the party or campaigner. Where appropriate, it will consider any inaccuracies or incomplete information in line with its Enforcement Policy.

All figures are rounded to the nearest £.
