It is not a claim about ambition; the ambition is set out in long-term statutory targets. The figures I have given show that these are substantial investments. As I will come on to clarify, there is some £770 million of support for low-income and vulnerable consumers in the financial year 2017-18, so there is no shortage of ambition or of investment. The hon. Lady and I share a strong belief in the importance of energy efficiency. I am trying to stress that what we are doing will increasingly focus on the most vulnerable, and, with public finances constrained, that must be the right priority.
