Political Parties

The Electoral Commission's Register of Political Parties lists the details of parties registered to fight elections in the United Kingdom, including their registered name. Under current electoral law, including the Registration of Political Parties Act, the Electoral Administration Act 2006, and the Political Parties, Elections and Referendums Act 2000, only registered party names can be used on ballot papers by those wishing to fight elections. Candidates who do not belong to a registered party can use "independent" or no label at all.
