The Electoral Reform Society (ERS) is an independent advocacy organisation in the United Kingdom which promotes electoral reform. It seeks to replace first-past-the-post voting with proportional representation, advocating the single transferable vote, and an elected upper house of Parliament. It is the world's oldest still-extant electoral reform campaign.
