Former Sainsbury's boss Justin King will lead an independent review of Thomas Cook after two children died on one of its holidays.

Mr King, who was Sainsbury's chief executive for 10 years, will investigate "customer health, safety, welfare, relations and crisis management practices" of Thomas Cook holidays after Christi and Bobby Shepherd died from carbon monoxide poisoning in Corfu in 2006.

In 2010, a criminal trial cleared Thomas Cook of blame and awarded damages against the hotel's owner. But in May, an inquiry said the travel firm breached its duty of care and that the children were unlawfully killed.

Thomas Cook and its then chief executive Harriet Green faced huge criticism over their reaction to the rulings. Thomas Cook accepted £3 million in compensation for lost revenue and legal expenses, while Ms Green accepted a £5.7m bonus, a third of which she donated to a charity chosen by Christi and Bobby's parents.

Justin King's review is likely to be completed in September.
