Chair of the National Infrastructure Commission (NIC) Sir John Armitt has written a letter to Chancellor of the Exchequer Philip Hammond, urging him to use the autumn Spending Review to commit to a “once-in-a-generation transformation” of the UK’s energy, transport and technology networks. In the letter, published on 13 May, Armitt laid down four key tests by which the NIC will judge the credibility of the government’s National Infrastructure Strategy, which is expected to be announced at the autumn Spending Review. The key tests are: a long-term perspective; clear goals and plans to achieve them; a firm funding commitment; and a genuine commitment to change.
