Boris Johnson is under mounting pressure to delay or scrap April’s National Insurance rise after George Osborne joined criticism of the hike.
The welfare-slashing ex-Chancellor warned the 1.25-point rise will come “at a time when real incomes are shrinking” in a warning shot to the Prime Minister.
Mr Osborne, who cut billions from Britain’s poorest, added: “Boris got the big judgment call on Omicron right… On the economy, I’m less clear.”
