My hon. Friend has done great work with many Members from various parties to establish that there is an appetite and need to tackle the problem exposed by the CMA, which has been going on for too long. In response to my letter, Ofgem has said today that it will work with consumer groups and come forward with a range of responses. I will look at them closely, as I know my hon. Friend will, and I am sure that the Business, Energy and Industrial Strategy Committee will, too. I have said clearly that the test of the adequacy of the responses is that they address the clear detriment that the authorities have identified.
