First, let me make it very clear to the House that every decision within this strategy is based on military advice—the advice of the service chiefs— as to how we better organise our capabilities. Secondly, in the end it will be for local authorities to rule on the exact proportion of affordable housing, but yes, we need more housing, and more affordable housing, in areas of shortage. Thirdly, we are consulting on the future accommodation model whereby we may be able to help service families in different ways. For example, rather than saying that their only option is to live on the barracks—on the estate—we could consider an option for them to have the money themselves to rent or, as has been suggested, to start to buy their own homes. We are looking at different ways of satisfying modern housing needs, but at the moment we are merely consulting on the different options.
