The Government have been clear that we will go as fast as we possibly can. We are removing the barriers that the hon. Gentleman discussed, but it is also right to say that it is an immensely challenging target. Going as fast as possible is the right thing to do, and we will work as hard as we possibly can to go as far as we possibly can by 2025. My ambition is absolutely to reach the number in our manifesto that the hon. Gentleman describes.
