Thank you. I know the Member will be aware from our conversations that I'm very keen to see strategic development plans. I wrote to all local authorities back in December, inviting them to look at how they can work together on SDPs. I've had some responses, and around joint development plans also, although not everybody has written back yet. I have also reminded them of the need to increase housing supply, and emphasised that new housing must contribute to the creation of cohesive communities. We don't want to see unacceptable impacts on social, economic or environmental infrastructure.
