Notes to Editors

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 and Scottish Parliaments.

2. Every political party that contested the Assembly election was required to submit a campaign expenditure return to the Electoral Commission. The deadlines for delivering spending returns depended on how much a party spent. As all parties spent less than £250,000 they were required to submit their returns by 5 August 2022. 

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

4. Candidates who stood in the election submitted their spending returns to the Chief Electoral Officer for Northern Ireland. Election agents for candidates were required to deliver an election spending return to the Chief Electoral Officer for Northern Ireland within 35 calendar days of the election result being declared.  Full copies of candidate spending and donation returns can be viewed at the Electoral Office for Northern Ireland. All figures are rounded to the nearest £.
