We have just heard about the land held by TfL, and Labour Members are seeking guarantees that houses built on TfL land will be properly affordable for people living in London. There is only one person who has guaranteed that that will be the case: my right hon. Friend the Member for Tooting (Sadiq Khan). If the hon. Member for Harrow East (Bob Blackman) wants to ensure that affordable houses are built on TfL land, I recommend that he votes for my right hon. Friend on Thursday.
