Predict09.eu is a prediction of the outcome of the June 2009 European Parliament elections and the resulting make-up of the next European Parliament. The prediction is based on a statistical model of the performance of national parties in European Parliament elections, developed by three leading political scientists: Simon Hix (London School of Economics), Michael Marsh (Trinity College Dublin), and Nick Vivyan (London School of Economics). The prediction will be updated each week until the elections on 4-7 June.
