BBC…Thomas Cook has collapsed after last-minute negotiations aimed at saving the 178-year-old holiday firm failed.
The UK Civil Aviation Authority (CAA) said the tour operator has “ceased trading with immediate effect”.
It has also triggered the biggest ever peacetime repatriation, aimed at bringing more than 150,000 British holidaymakers home.
Peter Fankhauser, Thomas Cook’s chief executive, said the firm’s collapse was a “matter of profound regret”.
Commenting as the company entered compulsory liquidation, Mr Fankhauser also apologised to the firm’s “millions of customers, and thousands of employees”.
The tour operator’s failure puts 22,000 jobs at risk worldwide, including 9,000 in the UK.
Transport Secretary Grant Shapps said the company’s collapse was “very sad news for staff and holidaymakers”.
He urged holidaymakers to be “understanding with staff” amid the “enormous” task of bringing people home.
Mr Shapps has announced that the government and CAA has hired dozens of charter planes to fly customers home free of charge.
The emergency operation, codenamed Operation Matterhorn, is aiming to bring home Britons currently on holiday with the firm.
On Sunday, empty aircraft had already started to be flown overseas, ready to bring British tourists back to the UK on Monday.
One of the world’s best known holiday brands, the business was founded in 1841 in Leicestershire by cabinet-maker Thomas Cook.
