I thank the hon. Member for his intervention; he makes the same point that others have made, namely that the polluter must pay. That is a core principle that I hope this Government will implement in the strongest possible terms, including bans on bonuses for water bosses. Let me finish my point about the Environment Agency. As I have already said, its response to me was quick and I hope that it has acted with all the resources that it can deploy. However, there are some concerns that it has played down the impact of this incident. The email that I received from the agency on the day talked about how the pollution will wash away once it reaches the Thames. The latest update that I have received says that the diesel is clearly dispersing around the river and that reports about it are declining in number. However, as I have just explained, the fact that the number of reports is declining does not necessarily mean that the damage has gone away. A key point is that I do not understand what baseline monitoring the Environment Agency was conducting in the first place in order for it to make the assessment that this incident has caused very little damage to the river. I have some specific questions for the Minister about the diesel spill; I appreciate that some of them might need to be followed up in writing. Can she advise us on how we can co-ordinate the investigations by multiple stakeholders into a single independent inquiry? If there is such an inquiry, will the Government ensure that it establishes a clear timeline of events and accountability at every stage? Will she enforce the principle that the polluter pays, which so many Members have discussed today, and ensure that any fines will go directly towards improving the River Wandle, rather than into a general fund? This incident has been truly shocking, not only to me and the local community but to the region as a whole, mostly because of its scale—that is what has caught the public’s attention. However, this kind of pollution happens every single day, not by accident but by design. The combined sewerage system has become high profile as a result of the campaigning against sewage that has been happening over the last year. However, we have heard less about the road run-off network, which makes an urban river like the Wandle especially vulnerable to such incidents. What goes down the drains can end up in our river, and when we think about a massive diesel spill such as this one, we should also think about all the types of pollutants that are running off our road network into our rivers every single day. At the moment, there is a lack of monitoring, so we do not really know what damage that pollution is having. We have a poor understanding of what the sewerage network looks like. Which drains connect directly into the river? Which ones go via the sewage treatment works? We do not really know the answers to those questions. There are also very limited mitigation measures. I know that fixing the entire infrastructure of this network would be difficult, but there are also measures that we can take further downstream. We have inadequate resilience, which could be addressed by the nature restoration projects that I referred to earlier. All the industrial adaptation that I also spoke about earlier—basically, how the river been canalised over the years—is choking off the river’s capacity to heal itself. We can see that the Wandle does not have much of a chance when there are 1 million inhabitants and a road network surrounding it. I am glad that the Government recognise that chalk streams need special protection, but I would love it if they recognised that urban chalk streams, such as the River Wandle, deserve even greater protection. The renewed attention on water quality in all of our waterways nationwide is extremely welcome. I know there are concerns that progress may be too slow: for example, in my area the major upgrades planned by Thames Water are not due to begin until 2035.
