Gordon Brown has called for the government to drop the energy price cap and temporarily renationalise energy companies which are not able to offer customers lower energy bills.
Writing in The Guardian, the former Labour prime minister compared the current cost of living crisis and soaring energy costs to the 2008 banking disaster.
In a broadside at Boris Johnson – who has been enjoying a trip to Slovenia in recent days – Mr Brown said that in a crisis leaders “don’t take holidays, and don’t politely hang fire”.
