The 2011 United Kingdom Alternative Vote referendum was the first to be held in Lincolnshire since the 1975 EC membership referendum and was only the second time that the people of Lincolnshire have been asked to vote in a referendum. The referendum asked voters whether to replace the present "first-past-the-post" (simple plurality) system with the "alternative vote" (AV) method for electing MPs to the House of Commons in future general elections. The proposal to introduce AV was overwhelmingly rejected by voters with all eight counting areas within Lincolnshire returning significant "no" votes.
