Political parties, campaigners and other groups have to report their finances to us.
- donations they’ve been given and loans they’ve entered into
- what they’ve spent on their campaign after an election or referendum
- their annual accounts
We publish all of the information we receive on Political Finance Online, so you can see what political parties, campaigners and other groups are doing.
The rules for publishing this information are different in Northern Ireland. At the moment, the legislation doesn’t allow us to publish any information about donations and loans from before 1 July 2017.
We also publish details of candidate spending returns after major contests, such as UK Parliamentary general elections.
