Come off it! Labour is pro-nuclear. This Prime Minister cannot get a single brick laid of a new nuclear plant. Energy security is not just about supply; it is also about reducing demand. Our housing stock is the least efficient in Europe. That is why Labour set out a plan to upgrade the 19 million British homes that desperately need it within a decade, saving families £400 on their energy bills and cutting UK gas imports by 15%, whereas all the Government have is a failed policy. Taking all their announcements together, it will take 75 years to deliver the upgrades that we need. That is a lifetime, when we need urgent action. When is the Prime Minister going to get on with it?
