It comes after the body of man believed to be the boat’s chef, Recaldo Thomas, a Canadian-Antiguan man, was recovered near the yacht on Monday. Among those missing are British tech magnate Mike Lynch after the Bayesian sank at around 5am local time on Monday when it was moored half a mile off the coast of Porticello. The cruise was reportedly a celebration of Mr Lynch’s recent acquittal on fraud charges in the US.

– Who is involved and why were they there? Mr Lynch and his 18-year-old daughter Hannah – who had recently finished her A-levels and was bound for Oxford University – remain missing. Also unaccounted for are Jonathan Bloomer, chairman of Morgan Stanley and insurance company Hiscox, and his wife Judy, a psychotherapist; and Chris Morvillo, a lawyer from Clifford Chance and part of the legal team representing Mr Lynch, and his wife Neda, who reportedly runs a luxury jewellery line. The body of a man believed to be chef Recaldo Thomas, a Canadian-Antiguan man working onboard, was recovered near the yacht.

Fifteen of the 22 people onboard – including Mr Lynch’s wife, Angela Bacares – were rescued after escaping on to a lifeboat. The Telegraph reported Mr Lynch had guests from the legal firm that represented him and his own company to join him on the voyage. Among others rescued were Charlotte Golunkski and her one-year-old daughter Sophie.

Ms Golunkski kept her daughter alive by holding the girl over her head in the water. – How did the boat sink? Ital.
