Housing and Planning Bill

When my noble friend sums up in this debate, will she look carefully at national parks? It is a pleasure to follow the noble Lord, Lord Campbell-Savours, who was my first opponent—I never felt confident enough to buy a property, in the national park or otherwise, in the constituency of Workington because he did such a good job there. Housing is a real problem, particularly for younger people who want to remain in rural areas, in or outside a national park. There are situations where planning permission has been granted for a major housing development only on the basis that a proportion of the houses would be given up for affordable social housing, but the developers then renege on that commitment. Will the Minister undertake to look carefully at such situations, to ensure that we are not going to lose, through the levy, that cohort of houses in national parks, or those affordable homes which have been agreed to but which the developers then find that they cannot afford to build?
