Rachel Reeves has said the government is facing difficult choices, as she promised she would not take risks with the public finances.
In her speech at Labour's annual party conference in Liverpool, the chancellor pledged to keep "taxes, inflation and interest rates as low as possible".
But hinting at further tax rises in November's Budget, she said the government's choices had been made "harder" by international events and the "long-term damage" done to the economy.
Reeves is facing a difficult Budget, with economists warning tax rises or spending cuts will be needed for the chancellor to meet her self-imposed borrowing rules.
