The latest model improvement has incorporated a Rural/Urban type for each constituency, using DEFRA data (England an Wales only). The relative success of each party in every R/U type is analysed; this then acts as an additional weighting on the predicted vote share.
As the Greens add more candidates their overall vote share is
increasing, now at 3.6%. The Lib Dems have settled at 22 seats, too few
for either a red or blue deal.
