The hon. Member will know that the infrastructure programme to upgrade our water and particularly our wastewater systems is the largest of its kind in the world. He can track progress against those infrastructure plans on the dashboard of the Water UK website. Good progress has been made. Just to give one statistic, when we came into office, less than 7% of overflows were monitored; the figure is now 100%. Those overflows will come down very swiftly in the coming years. But there are particular issues with particular companies, and I will make sure that the Secretary
of State has heard his particular concerns about these aspects of Thames Water, as the next questions is not until 9 May.
