LShift swingometer

We apply a simple "uniform national swing" model to predict what kinds of Parliament might result from different national vote shares. Move the mouse over the chart to use it; the position on the chart represents national vote share, and colour represents the share of seats. The mid-point of the Y in the centre of the chart represents the point where each party gets an equal share of the vote; the red background at that point shows that Labour would gain most seats under such circumstances, and would in fact be only a few seats short of a majority.
