More than 1,000 of TGI Fridays’ UK staff will be made redundant despite a rescue deal from the owners of restaurant group D&D London.

They have bought the UK operator of the American-themed chain, after its owner fell into administration last month.

The deal will save nearly 2,400 jobs at 51 of the 87 restaurants.

However, the administrators, Teneo, said the other branches 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.

She added she was “devastated for our colleagues who will be leaving TGIs and thank them for their loyalty and contribution during their time with us”.

The buyers Breal Capital and Calveton UK already own restaurant chains Byron Burgers and Vinoteca as well as restaurant group D&D London.

A spokesperson for the new owners said it wanted to “both modernise the business and capitalise on the heritage of this iconic brand”.
