The owner of restaurant chains Wagamama, Frankie & Benny's and Chiquitos are to shut 23 venues by the end of the month.
The Restaurant Group (TRG) announced on Tuesday that they had brought forward their programme to close loss-making restaurants as part of the company's ongoing cost-cutting efforts.
It follows a previous statement in March revealing that 35 of their restaurants would be disposed of in a measure to save the firm around £5 million per year in costs.
