Strong Transition Model (28-Oct-2007) Our new model builds on Electoral Calculus' unique prediction model to allow for effects such as incumbency and local party strength. This is useful for predicting the Liberal Democrats in their current weakened state and avoids the prediction of zero seats.
Find your new constituency (5-Oct-2007) We now have a helpful tool which can tell you which new consituency you live in. All you need to know is your postcode or local council ward name.
This website explains where these predictions come from, and shows you how you can make your own predictions at any time. There are also detailed predictions of every seat, including a list of target vulnerable seats, and a complete nationwide list of seat predictions.

New Boundaries All predictions on the site are now based on new constituency boundaries which were finalised in July 2006. These boundary changes take approximately 10 seats away from Labour and gives them to the Conservatives. The House of Commons will have 650 seats, so 326 seats are required for a majority.

Also freely available are data files containing the seat-by-seat results of the last five elections.
