Thomas Cook UK Plc and associated UK entities have entered Compulsory Liquidation and are now under the control of the Official Receiver.
The UK business has ceased trading with immediate effect and all future flights and holidays are cancelled.
A dedicated support service is being provided by The Civil Aviation Authority to assist customers currently overseas and those in the UK with future bookings.

Note that as I write this the CAA webpage is broken. Maybe it's overloaded or maybe they haven't quite got it up and running at 2.45am UK time.
