Chancellor said to be planning measures including raising employer NI contributions and capital gains tax rates. We consider the likelihood of each and the potential for a row

During the general election campaign, Paul Johnson of the Institute for Fiscal studies repeatedly accused both main parties of indulging in a “conspiracy of silence” over their economic policies. Neither Labour nor the Tories would admit, he complained, that if they won they would have to announce huge tax rises or spending cuts to restore the public finances to anything resembling good health.

On Wednesday, 118 days after Labour won the election, Rachel Reeves will prove Johnson right. In her first budget she will spell out plans to raise an eye-watering sum of about £40bn from tax rises and spending reductions to wipe the slate clean and to pump funds into public services. She will also confirm changes to debt rules that will release up to £50bn more to borrow for long-term investment in new national infrastructure.
