Yes, the drainage problem is important. I have no doubt that increasing urbanisation has impacts on our planning framework, which is why we have been looking at PPS25, to try to ensure that we properly manage the risks of building on floodplains and of the kind of developments that are taking place. It is one of the issues that we can pursue. My hon. Friend the Minister for Local Government is leading a group of Ministers across Government to ensure that we look at the issues. What is also important is that we learn the lessons from such events, and we absolutely mean to do that, so that we can best inform our policy for the future.
