In fairness to Gordon Brown, it is refreshing to see a former prime minister intervene in contemporary politics constructively, in an effort to offer solutions to a crisis, rather than simply to denigrate one of his successors, as has become prevalent among former Tory leaders. Nor are Brown’s prescriptions for dealing with the energy crisis, despite their including temporary nationalisation, knee-jerk Corbynist opportunism.

That said, despite Gordon Brown’s intervention representing a serious contribution to the energy debate, in the final analysis his arguments are unpersuasive. He highlights the astronomic figures for energy price inflation published by Cornwall Insight and recommends a pause in any further increase in the energy price cap, a review of energy companies’ profit margins negotiation of separate company agreements to keep prices down. If companies cannot meet government requirements, Brown would apply the same policies he used with the banks in 2009: guaranteed loans, equity financing and, as a last resort, temporary nationalisation.
