Sustained lobbying by local authorities and the housing sector has yielded a significant result.
You don’t ask, you don’t get. Massive costs to the public purse and social dislocation are not vote winners.

The prime minister, some of her key aides, the chancellor and housing minister are all ex-councillors. They all started their political careers in London local authorities.
The May administration has its roots in town halls and the realities of ward meetings. Not the Bullingdon Club.
The rent cut is still a reality, as are benefit cuts. But recognising the vital need for partnerships and a willingness to take pragmatic decisions will help the housing sector and low income residents.
This is a well timed step in the right direction.
