The member of the House of Lords who asked this question was the Bishop of Derby the Rt Revd Libby Lane and the response came from Baroness Joanna Penn, a Government Minister. The two comments which have been received so far suggest the response from Rachel Penn are inadequate that can be seen here and here is the text.
Bishop of Derby: To ask His Majesty’s Government what assessment they have made of the case for allowing local authorities to set their own right-to-buy discounts to reflect local circumstances.
Baroness Penn: The Government remains committed to the Right to Buy, which has helped over 2 million social housing tenants to become homeowners.
The Right to Buy is a statutory right for eligible local authority tenants across England, with the discount formulae set in regulations. This approach already recognizes higher property prices in London with a higher maximum discount for any sales inside London. This ensures a consistent offer for tenants across the country.
