The Senedd now uses a voting system called the 'closed proportional list system' to elect Members. Most candidates who stood, represented a political party, with just 30 individual candidates standing.
As a result of this, political parties submit spending returns that cover their spending across Wales, whilst independent candidates submit individual spending returns. Independent candidates had a deadline of June 12, 2026, to submit their spending returns. These are published here today.
Political parties who spent less than £250,000 had a deadline of August 7, 2026, to submit their spending returns and parties who spent over £250,000 have a deadline of November 7, 2026. These will be published in due course.
The data has been taken from the spending returns that candidates submitted to Returning Officers. We publish this information as it appears on the candidate’s return so that there is an accurate record of what was reported.
