A Thomas Cook boss has apologized after a video emerged of employees cheering him and other executives at the company's Condor subsidiary after securing a rescue.

"The reaction from myself, Condor management and staff was a pure relief that Condor could continue to fly and more cancellations within Group Airlines were prevented. However, I am aware that this video was timed and I apologize . "

"Thomas Cook directors have to explain why the British airline had to be shut down, but the German was allowed to continue operating," said Secretary General of the Balpa Pilots Union, Brian Strutton.
"How was it funded because it looks like there's nothing left in the coffin for UK employees? And why couldn't the British government give the same type of bridge building as the German government when it was well known that Thomas Cook had a Chinese buyer lined up? It's a national scandal. "
