In her speech to the Tory conference, Mrs Badenoch was expected to warn that "something is going to break" without better economic growth in Britain. She accused the Burnham government of wanting to "wind back the clock to failed ideas of the past" after it unveiled plans to nationalise water companies and increase regulation on landlords.
Central to the Conservative leader's pitch are plans to cut tens of billions of pounds from the benefits bill, a move that Mr Burnham has so far avoided pledging. The Tories have also promised to halve employer National Insurance contributions for young people, a direct attempt to reduce the tax burden on businesses and workers in London and beyond.
Ahead of the speech, Deputy Conservative leader Alex Burghart told Times Radio: "There's a view on the Left, which is basically that everything you've got is up for grabs by the taxman, and we're just arguing about what they're going to take next."
The tax burden is at a historic high, and Chancellor John Healey has not ruled out further tax rises in the Budget due at the end of the month. Mrs Badenoch framed her party's offering as a "battle for the soul of the nation" at the next general election.
