I congratulate my hon. Friend on securing this debate and making an excellent speech. On her last point, as far as I understand it, Berkeley constructed no affordable housing last year, and for Barratt Homes, Persimmon and the others in the top four, the figures are around 18% to 20%. It is a complete scam. The amount of money they are taking out at the top, and not just for executive pay or shareholder pay—I have no problems with shareholders receiving dividends and so on—is at the expense of much-needed social and affordable housing. The whole viability element of the planning system is a complete scam and should be done away with.
