Thomas Cook One of the world’s best known holiday brands, Which was founded in 1841 has collapsed after last-minute negotiations aimed at saving the 178-year-old holiday firm failed.
It has also triggered the biggest ever peacetime repatriation since Dunkirk aimed at bringing more than 150,000 British holidaymakers home.
The tour operator’s failure puts 22,000 jobs at risk worldwide, including 9,000 in the UK.
The government and CAA has hired dozens of charter planes to fly customers home free of charge.
The emergency operation, codenamed Operation Matterhorn, will aim 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 home on Monday.
All Thomas Cook bookings, including flights and holidays, have now been cancelled.
All customers currently abroad with Thomas Cook who are booked to return to the UK over the next two weeks will be brought home “as close as possible” to their booked return date, the Department for Transport (DfT) has said.
Customers will be brought home to the UK on special free flights or booked onto another scheduled airline at no extra cost.
