Because Labour MPs tend to represent those with lower voter registration figures, each Labour MP requires 114,0000 people to be elected. A Tory, under this system, requires 97,000.
The result is obvious. The system biases the Tories. It is estimated that they will gain 22 seats they do not deserve as a result.
This is gerrymandering. Tory corruption reaches far and wide.
The bit that Peter Kellner – the original source – brushes aside is that his population numbers include non-citizens. Whether legal or illegal.
