The wife of one of the men to die in the Titan submarine disaster has blamed 'ego and arrogance' for the deaths of her husband and son.

Christine Dawood lost her billionaire British-Pakistani husband Shahzada, 48, and son Suleman, 19, on board the Oceangate vessel on a tour of the Titanic wreck in June 2023.

OceanGate CEO Stockton Rush, 61, British businessman Hamish Harding, 58, and former French navy diver Paul-Henri Nargeolet, 77, also died when the submarine imploded almost 4km under the sea, instantly killing everyone on board.

Now Ms Dawood, who was born in Germany but is from Surrey, is calling for proper regulation of the sector after concerns were raised about the safety of the vessel in the first place.

Criticising Stockton, who she said enticed her Titantic-obsessed husband and son on the $250,000-per-head trip, she told the BBC: 'I guess the American way of talking and presenting themselves is very different to ours, so I just thought they are a lot more egocentric.
