The right hon. and learned Gentleman is making an interesting speech. I have been trying to keep pace with all his asks of the Chancellor in terms of costs—it is a serious list of asks. Does he not think there is a need for a serious debate, costed out, about the cost of decarbonising our transport network in the future? I agree with his proposals for investment in Leeds, and for Letchworth Garden City and his constituency. Other things are also needed for London and the funding simply is not there within the DFT’s budget, so an urgent plan to change that is essential.
