I thank the Minister for giving way. The Minister for Housing and Planning wrote to me last month to confirm that the Government believes that

“the best way to encourage affordability”

—his term—is by “increasing supply”. I thank the Minister for his description of the supply he is bringing. If that is the sole policy driver, I would like to know what formula the Government are using to deliver that market-based policy. To put it another way, by what level will private rents in London come down with the delivery of that 42,000?
