In my constituency of Horsham, we are almost entirely surrounded by other areas that, for one reason or another, have constrained housing targets—they have areas of outstanding natural beauty, are in national parks or are already built up. As a result, under the duty to co-operate, Horsham has to take a very unfair proportion of housing to serve the whole area. Does the hon. Gentleman agree that the duty to co-operate system needs to be revised to stop freak results happening in constituencies such as mine?
