The Electoral Commission was established under the Political Parties, Elections and Referendums Act 2000. Its functions include the regulation of party and election finance in the UK and the promotion of greater participation in the electoral process. Documentation on the site includes consultations, annual reports, and guidance for electoral administrators, candidates, agents or parties, and voters. 

Since the 2010 UK general election the Deputy Prime Minister has been responsible for political and constitutional reform, including electoral reform. Before then the Ministry of Justice was responsible for the legislative framework for UK and European parliamentary elections and national referendums. This archived section of its web site has guidance for electoral administrators, including a list of secondary legslation for the Electoral Administration Act 2006 and keeling schedules showing significant amendments to the Representation of the People Act 1983 and the Representation of the People (England and Wales) Regulations 2001.
