To stray a little off topic, it should be interesting to see how the new housing benefit cap will affect London.
(Basically, if I get it right, it'll be set at around £400 per week, instead of at the median rent for a particular area? Which means that councils like Westminster are already talking about housing families out in the suburbs rather than downtown.)
Will this cause a drop in rents in the capital, as the benefit was basically a subsidy/nice little earner for landowners? Or are there enough rich folk to take up the slack and large segments of the city will be even more like Manhattan, post rent control?
