Metropolitan open land is a status that is specific to Greater London, but it holds the same weight, effectively, in Greater London as green belt. If the hon. Lady were to consult the London plan, similar circumstances should apply in terms of its de-designation.
My hon. Friend the Member for Bromley and Chislehurst (Robert Neill) showed his huge experience in this area in his contribution. He made a number of constructive suggestions, which we will certainly look at.
My hon. Friend the Member for North Warwickshire (Craig Tracey) raised issues around the calculation of assessed need and in particular in relation to migration. The population projection figures do assume a fall in migration. While migration is clearly a factor, about a third of household growth nationally is due to net migration, so even if there were no migration into the country, there would still be significant pressure for more housing.
My hon. Friend the Member for Fylde (Mark Menzies) made two very powerful points. The first was about build-out rates. As a Government, we want to listen to developers and to address evidenced concerns about things that are slowing up development, be it pre-commencement conditions, the time it takes to agree section 106 agreements or concerns about utilities. However, if we do all those things, I think we have a right to turn to the development industry and ask what it is going to do to raise its game in terms of the speed with which it builds out. My hon. Friend also made another critical point, which is that, when we talk about affordable housing, yes, council and housing association housing are a part of that, but what most of our constituents want is a home that is affordable to buy, and he was absolutely right to stress that.
My hon. Friend the Member for Hazel Grove (William Wragg) made the powerful point that this problem is going to take time to solve. There is no quick switch that anyone can throw to deal with it. He rightly wanted to hear more about what we can do to focus development
on brownfield land. The Act that received royal assent earlier this year set up the principle of brownfield registers, where local authorities will set out clearly the brownfield land that is available in their areas and suitable for housing development.
My hon. Friend the Member for Croydon South (Chris Philp), and Opposition Members as well, referred to resourcing for planning departments, and that is something the Government have consulted on. As part of the White Paper, we will want to come forward with a response to that consultation.
