I thank the hon. Lady for that question. We recognise that this is an issue under intense speculation. We will publish a strategy that will set out many of the answers to the questions she is posing. What we have said is that we will put affordability and fairness at the heart of our reforms to reach net zero. The fact is that everyone in this House agreed with us when we set that target. For example, we have put in place plans to bring in electric vehicles by 2030. These will require changes not just in how we spend, but in our tax and regulatory system. The answers will come in due course.
