While agreeing with the Minister that there may be marginal cases, particularly where the green belt is not green, may I ask whether he agrees that it is high time he took legislative powers, which were promised by his predecessor, to do something about the pressure on space in London caused by office blocks? Is he aware that a year ago there was 9 million square feet of empty office accommodation or space for which building permission had been given? Is it not time that he did something about this pressure on resources?
