Mayor Ken Livingstone has won a battle to increase the number of social rented units on a scheme in west London that had become a test of his affordable housing policy.

Last year Conservative-run Hammersmith and Fulham council made Genesis Housing Group cut the number of units at its BPTW-designed scheme in Acton, visualised here, from 148 to 65. But after pressure from the Housing Corporation and Livingstone, the council has approved a scheme containing 104 social rented units. Last week Livingstone lifted his threat to refuse permission for the scheme.
