Hard-pressed Brits face a National Insurance hike on April 6 after Boris Johnson ruled out claims he is preparing a U-turn.
Downing Street said the tax rise from 12% to 13.25% will happen “no ifs, no buts” after claims the PM was “wobbling” over it to save his job.
The PM’s deputy spokesman said the Prime Minister and Chancellor were “fully committed” to the £12bn-a-year hike and “we’re introducing it in April”.
