My hon. Friend is right to highlight London. He will know from his experience and will have heard from his constituents that some of the greatest need in our country is in our great capital city. There is a need for greater co-operation, but the statement of common ground will help significantly by bringing greater transparency and more certainty, and it will force councils to co-operate much earlier in the process. One of the issues with the current duty to co-operate is that it tends to happen at the end of the process. This will ensure that that important dialogue begins right at the start.
