LONDON Mayor Boris Johnson joined forces with Tory pal George Osborne yesterday to launch a massive new attack on low-rent homes in the capital.

Fears mounted as they revealed plans for a London land commission to identify “all the public-sector brownfield land” in the city and earmark it for development.

Only a year ago Communities Secretary Eric Pickles revealed council housing was included in his definition of “brownfield” — a phrase more usually linked to former industrial land.
