I intervened in this Oral Question debate last week to say: We are seeing more erratic weather patterns and some increasingly severe floods. Is the plan for sustainable drainage systems speeding up? Will we see that in the water White Paper?

The recent issues in Monmouthshire—we are terribly sorry for the people there; they have had a dreadful time over the past few days—make us even more determined to support the delivery of high-quality sustainable drainage systems to help us manage flood risk and adapt to the effects of climate change. National planning policy therefore makes it very clear that developments of all sizes are expected to make use of sustainable drainage techniques where the development could have drainage impacts. I have seen some fantastic examples of that when visiting housing sites around the country. Not only can it be done, but in a way that enhances the environment for local residents. We are considering what further changes need to be made to planning policy.
