Henry Zeffman: Andy Burnham and his chancellor have a battle on their hands

Today's inflation figures underscore that the economy is the biggest challenge facing Andy Burnham. It is only 42 days until John Healey's first Budget, and there is increasingly apparent concern at all levels of the government and Labour Party about how that Budget can - or, as it may prove, cannot - substantiate Burnham's rhetoric about offering the biggest change in British politics in 40 years. Much of the tricky economic environment, yes, is driven by global factors including the persistence, and to some degree worsening, of the conflicts in the Middle East and Ukraine. And the AI boom pushing up borrowing costs is another issue affecting many countries.
