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 family of two young children who died from carbon monoxide poisoning while on holiday in Corfu have said they were not consulted by Thomas Cook about the firm's £1.5 million donation to Unicef.
Wakefield Labour MP Mary Creagh, who has been supporting the family, said she has spoken to the children's parents, Neil Shepherd and Sharon Wood, and they believe this latest move is all about the firm and not them.
Ms Creagh said: "Their feeling is that this once more is not about them, it's about Thomas Cook.
"Thomas Cook have not contacted them about this."
Ms Creagh said the family have a particular children's charity they have been supporting and to which relatives and friends have been donating in Bobby and Christi's memory.
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.
