Sadiq Khan is ‘closely monitoring’ the delivery of the affordable homes programme in London, amid warnings that inflation could make development unviable.

The mayor, who administers more than a third of the £11.5bn programme’s funding, is aware of the ‘pressure’ on developers, a city hall spokesperson said.

A spokesperson said: “His team are closely monitoring scheme delivery and the state of the wider homebuilding industry, including factors that might impact programme delivery.”
