Nearly 2,400 jobs at TGI Fridays' UK business have been saved after the American-themed restaurant chain secured a rescue deal.
The owners of restaurant group D&D London have bought the chain, after its UK owner fell into administration last month.
However, more than 1,000 TGI Fridays UK staff will be made redundant as only 51 of the 87 restaurants are being bought under the deal.
The administrators, Teneo, said the other restaurants have been closed with immediate effect.
TGI Fridays UK said it was working with landlords on a deal to save the closed restaurants.
"We are doing everything possible to retain our team and support those impacted," said chief executive Julie McEwan.
