Budget supermarket Budgens is to close 34 of its stores, resulting in the loss of 800 jobs.
Food Retailer Operations Limited (FROL), one the supermarket chain’s operators, was put in administration last month.
A total of 815 staff have begun the redundancy process.
FROL only bought the stores from the Co-operative Group in July.
At the time the firm said "there are no planned redundancies" and stores will continue "trading as usual".
However PwC was appointed as administrator last month and the accountancy firm has failed to find a buyer for the group.
Mike Denny, joint administrator at PwC, said: "Unfortunately, we have been unable to find a buyer and it is not commercially viable to continue trading the stores.
"We are working closely with the Co-op, Usdaw and the relevant government agencies to ensure that all employees receive the maximum levels of practical and financial support through the redundancy process."

A Budgens spokeswoman said: "Budgens is a brand which operates 150 stores as a symbol group. The business is performing very strongly.
"In July 2016 The Food Retailer Operations Limited (TFR) bought 36 stores from the Co-op and traded them under the Budgens brand.
"TFR have recently gone into administration. This means they are currently in consultation with their 800 colleagues.
"We are disappointed that TFR are in this position, but this does not affect Budgens or its colleagues."
