Rachel Reeves has condemned a series of Treasury leaks ahead of her recent Budget, calling them 'inaccurate, damaging, and unacceptable’. She insisted the disclosure suggesting that she had abandoned plans for an income tax rise was not an authorised briefing but a leak, which undermined confidence in her commitment to restoring fiscal 'headroom.' Reeves confirmed that a full inquiry had begun, alongside a review of Treasury security processes to prevent further breaches. She expressed frustration at the volume of speculation surrounding the Budget, stressing the need to restore integrity to fiscal announcements. MPs also questioned her on her decision to freeze income tax thresholds for three more years. She denied breaking Labour’s manifesto pledge, arguing that the promise referred specifically to tax rates, while acknowledging that the freeze would mean working people paying more. She said she and the prime minister had jointly decided the measure, rejecting suggestions she had been overruled.
