My hon. Friend is absolutely right. I thank her for raising that important issue and for her work on it and her passion. She is right to point out as well that the Environment Agency budget was cut by half under the previous Government, which left it powerless to clamp down on polluting water companies. We have been clear that the amount of sewage discharged into our waters is unacceptable. That is why we have already banned unfair bonuses for water bosses, introduced tougher automatic penalties to clamp down on pollution and secured money to upgrade storm overflows across England. But we are not stopping there; we will also release a water White Paper which will set out long term reforms to strengthen regulation, tackle pollution and accelerate the delivery of water infrastructure.

The hon. Gentleman is quite right: of course we want a regulator with teeth, able to identify the exact source of pollution. As we have already said about our water White Paper, there will be a regional element it order to be in more detail at those particular catchments to identify the main source of pollution in each catchment and, therefore, the best actions to take to address it.
