Where's the graphic from ? Is it not geographic in nature which would indicate the SW is libdem? I'd assume Bromley or chiselhurst most likely to be Tory.
Yeah, the blue hexagon on the western edge is likely Uxbridge & South Ruislip. The pre-boundary change seat of Uxbridge never went red under Blair/New Labour.
Assumptive London MPs after the election. Only rich sw toffs represented by Tories.
