Political opponents of London’s mayor have questioned new figures which show Sadiq Khan is on track to start 17,000 genuinely affordable homes across the capital this year.

Between March and December 2019, 12,546 genuinely affordable homes were started in London, nearly three quarters (74%) of the mayor’s annual target, according to data from the GLA. This is a hefty increase on the 42% that had been started by this stage of 2018-19.
