Donations to political parties, including sponsorship, are regulated by the Political Parties Elections and Referendums Act 2000.
Donations of over £500 are only accepted if they are from permissible donors.
These are: individuals on a UK electoral register, UK Trade Unions, companies incorporated within the EU and registered and trading in the UK, Limited Liability Partnerships, UK unincorporated associations and UK building or friendly societies.
Donations of more than £1500 from the same donor in a calendar year are required to be reported to the Electoral Commission. This applies to single donations or cumulative smaller donations which exceed £1500 in the calendar year.
The name and address of the donor and the amount of the donation will be published on the Electoral Commission website. Addresses of individuals are not published.
