Political Developments
Prime Minister Andy Burnham told ministers he would lead a “cost-of-living Government” after announcing an £850 million tax cut on electricity bills. Using his first Cabinet meeting, Burnham said ministers must give people “a sense that help is coming” and vowed to show how policies would be paid for.
AJ Bell analyst Russ Mould commented: “Andy Burnham is now confirmed as the nation’s seventh prime minister in 10 years, with John Healey as our ninth Chancellor of the Exchequer in the same time span, and the electorate and financial markets alike now wait to see what policy initiatives may follow.”
Chancellor John Healey, addressing Treasury staff for the first time, said he wanted to build “new hope” for Britain. He promised fiscal control as his “first duty” and the “bedrock of economic stability”, pledging “principles not political buzzwords” and a “new era of devolution and public control”.
