Workers could be clobbered by Rishi Sunak as he considers a £10billion "stealth" tax on wages.
The new Prime Minister is looking at extending a freeze on income tax thresholds, which would leave millions paying hundreds of pounds extra in tax.
As chancellor, Mr Sunak froze the personal allowance, the amount workers can earn without having to pay income tax, at £12,570 for three years until 2026.
