The London-based Israeli restaurateur Yotam Ottolenghi said his business was on its “knees” as a result of new social distancing restrictions introduced into the capital last week.
“We just don’t have customers coming through the door,” he said.
Mr Ottolenghi, whose six retaurants include Nopi in Soho, was speaking on Radio 4's Today programme before the Chancellor Rishi Sunak announced new support for business on Thursday.
With the national furlough scheme for staff ending this month, additional support had been available only to businesses forced to close in areas placed in the tier-3 category where Covid infections are “very high”.
