I agree London in general is a Labour stronghold in the obvious areas e.g. Islington Hackney etc.

I was just speculating that we could see a slump in parts of affluent central London as businesses go bust or downsize their office space or simply move away to smaller cheaper properties. This would then have a knock on effect with the services industries e.g. sandwich shops dry cleaners etc.

It's just guess work.

I doubt Mayfair and Chelsea will be impacted but overall I an see a big change in how London looks coming.
