This tool allows you to see how past elections may have gone had certain parties been in an electoral pact with each other. It is not a tool to predict future elections.
Caveats:
- This tool makes quite often wrong assumptions about how voters would vote should their preferred candidate not stand.
To use this tool, choose a lead alliance member (typically The Conservative Party or the Labour Party), and then choose however many other alliance members you would like. Lead Alliance Members do not stand down in any seats.
New: Try choosing "2017" for the General Election Year.
