Proposals aim to push people into work, but charities say families are still paying price of austerity cuts and rise in cost of living

People claiming universal credit (UC) would have their payments cut by a third if they have not paid enough national insurance, under a Conservative plan condemned by one charity as “a fast track to increased poverty”.

Under the proposals, those who receive this “subsistence allowance” would have it paid into a dedicated debit card that would prevent from them buying alcohol or tobacco, based on an Australian system that was scrapped after trials found limited evidence it changed behaviour.
