The Institute for Fiscal Studies has published its yearly Green Budget, weeks ahead of Chancellor Rachel Reeves’s first fiscal event. It’s grim reading, for both the government and the public. For Labour to make good on its promise to avoid ‘austerity’, taxes are going to need to go up significantly: by £25 billion, the IFS’s reports, and that’s just to ‘keep spending rising with national income.’ Can Reeves square the circle?  James Heale speaks to Katy Balls and Kate Andrews.  Produced by Oscar Edmondson.
