Tectonic Voter Migrations

The graphic shows how voters have switched allegiance between the parties since 2010. One hundred typical voters are shown, with the arrows showing their various migrations from one party to another. "Lost" voters to a party are coloured grey, and "gained" voters carry a white cross.

The graphic makes clear the collapse in Lib Dem support and the growth of the minor parties. It also contains some bad news for the Conservatives.

Battleground April 2015

UK Electoral Battleground for 2015

Currently there is about a 80% chance of a hung parliament in 2015. This detailed diagram of the electoral battleground maps out the several possible outcomes. The growth of SNP support in Scotland creates a genuine four-party system at Westminster with a range of possible coalition permutations. Conservative support is given by the horizontal axis, and Labour support by the vertical axis. The current support position (Con 33.6%, Lab 31.7% at 25 April 2015) is shown by the circular blue marker inside the "Nat choice of Con/Lab" zone, where the SNP has the balance of power.

Technical notes: Map only shows movement for the Conservative, Labour and Liberal Democrat parties. It assumes the votes for other parties, including UKIP and the SNP, are fixed at current support levels. UKIP are not currently to predicted to win many seats, so they are not yet a factor in coalition permutations. Since other parties have 28% support nationally, the map is missing the top-right corner where the Conservative plus Labour total would be more than 72%.
