Three colours are mixed for the three major parties in each of 633 mainland parliamentary constituencies on an equal land area map — software by author on an Archimedes computer.
The map is annotated by the (occasionally obscured) full names of constituencies. It shows a very different picture to the cartogram (Plate LXXI). England is covered by the blues, greens and purples that spell out a Conservative landslide; while the yellow and lime greens of Scotland and Wales show us Liberal country. The red of the Labour party is relegated to a few cities, only really visible in the Scottish, North-East, Welsh and Yorkshire coalfields. The map is deceptive, the population cartogram actually giving the true spatial balance of the votes.
