The brilliant thing about their table is that it feeds directly into the regional predictor on Electoral Calculus.
The predicted election result is Con 291 (+83), LD 94 (+27), Lab 233 (-113), Nat 11 (+3).
One to watch on election night is Oliver Letwin, who is here predicted to lose his seats to the LibDems.
This is of course not an exact science – UK Polling Report is predicting Con 262, LD 111, Lab 245 based on the same data.
Hopefully the LibDems will manage to get the electoral system changed if they hold the keys to Number 10, as seems likely based on this.
