Communities secretary James Brokenshire has joined the chorus of disapproval around segregated playing areas in mixed-tenure developments and said planning guidance will be tightened to ensure social housing tenants are not discriminated against.

Brokenshire stepped in after London mayor Sadiq Khan repeated his call for the abolition of separate entrances for residents of different tenure living on the same development.

Brokenshire said planning guidance would be “toughened up” and a new Design Manual will promote best practice in inclusive design.
