About the Project

Bunch of election leafletsElection leaflets play a central role in British general election campaigns. They tell prospective voters what political parties – and their candidates – stand for, how they will serve their local communities and the nation, and they provide information about a party’s chances of success. Even with the rise of social media, traditional election leaflets remain the most common way that citizens engage with politicians during a general election campaign. More voters report receiving a leaflet than any other type of campaign contact, and political parties spend more money on designing and distributing election leaflets and other unsolicited communications than on any other campaign activity.

Despite the importance of election leaflets, we know very little about the nature of these communications. Citizens across the country receive thousands of leaflets and direct mail from political parties at election time. But because parties often target these materials to particular voters and constituencies, we don’t necessarily know what parties are talking about elsewhere. The OpenElections project aims to increase the transparency of British general elections by allowing citizens to analyse what political parties and candidates talk about in their election leaflets across the country. Visit our Leaflets page – we have more than 8,000 leaflets for you to explore.

OpenElections is funded by the Biotechnology and Biological Sciences Research Council, but it is powered by you. You can help us by uploading new leaflets or by using our coding tool to help us identify the messages contained in the leaflets. Together we can increase the transparency of our elections – one leaflet at a time.

Frequently Asked Questions

  • Where does the data come from?

    Images of election leaflets received by citizens across the country are photographed and uploaded to, run by Democracy Club, or directly to Our team has coded thousands of election leaflets distributed since the 2010 general election for you to explore in our archive.

  • Do you have all the leaflets distributed in a general election?

    Unfortunately, no. While our archive includes a large number – and a wide range – of electoral communications, this is not a complete count of leaflets distributed during the campaign. Many of the leaflets that are distributed are of the same design, distributed to households across the country, but we acknowledge that our data captures only a small portion of all leaflets distributed.

  • How are you funded?

  • How can I contribute to the project?

    Our project relies on the help of citizens like you! Help us code new leaflets for the archive by clicking on ‘code a leaflet’ at the top of the website. You will be shown some images of an election leaflet. Using the options on the side, you can select what messages and issues the leaflet mentions. We have provided short descriptors that appear as you hover over the issue area to help. You can also upload any leaflets you receive by clicking on ‘upload a leaflet’ at the top of the website.

  • I have found an error with the coding, what should I do?

    If you have found an error with the coding of a leaflet, you can contact us by selecting ‘Report a Problem’ under the leaflet’s details.

  • How should I cite the data?
