That is a very important point. I will come to it, but it is important to highlight that the amount of green belt in this country has increased in recent years. The overall amount has gone up substantially. That is due in large part to the introduction of a green belt in the north of England, but it is also the case—we should always stand back and consider this—that, in terms of pure hectarage, the amount of green belt
has increased. The hon. Lady makes a very important point, and ultimately we have a decision to make on green belt.
The hon. Member for Greenwich and Woolwich (Matthew Pennycook) on the Opposition Front Bench made the important point that some parts of the green belt do not have the same aesthetic quality as others. Moreover—this has been in the NPPF for a substantial amount of time—there will be exceptions. In certain instances, buildings will need to be built for farms and for forestry, and consideration will have to be given to elements that most hon. Members and people out there will accept are reasonable. My point is that there has to be flexibility. The NPPF provides flexibility while making significant statements about the importance of the green belt, which is absolutely vital.
