ITV News has learned that a man convicted over the gas deaths of two children in Corfu has been working at another hotel used by Thomas Cook.
George Chrysikopoulos was found guilty of negligent manslaughter by a Greek court and sentenced to seven years in prison.
Following ITV News' investigation, Chrysikopoulos was sacked by the hotel yesterday at the insistence of Thomas Cook.
The boss of Thomas Cook will meet the family of two young children killed by carbon monoxide poisoning in Corfu later today.
Peter Fankhauser, chief executive of the travel company, has admitted the company failed in its handling of the tragedy and pledged to help the children's parents move on with their lives.
Christi and Bobby Shepherd died at the Louis Corcyra Beach Hotel on the Greek island in 2006 while on a Thomas Cook holiday.
Fankhauser issued a public apology to the children's parents as the firm seeks to halt a mounting crisis over its reputation following the way it has treated the family since the incident.
The boss of Thomas Cook said he is "deeply sorry" over the deaths of two British children killed by carbon monoxide poisoning in Corfu.
Kristine Williams, 61, claims she was electrocuted and 'thrown across the room' after accidentally touching the wires at a hotel in Cuba.
