The chair of Morgan Stanley International is among the missing in the yacht sinking as the search operation continues.

• A luxury yacht sank off the coast of Sicily on Monday, and among those missing is the chairman of Morgan Stanley International, Jonathan Bloomer, according to Sicily's civil protection agency.
• On Tuesday, the search for British tech entrepreneur Mike Lynch and his 18-year-old daughter Hannah continued as rescue efforts were renewed.
• On Monday at 4 a.m. local time, the 56-meter sailing boat "Bayesian" was struck by a severe storm while carrying 10 crew members and 12 passengers on board.

On Monday, a luxury yacht sank off the coast of Sicily, and among the missing was Jonathan Bloomer, the chairman of Morgan Stanley International.

The civil protection agency in Sicily announced on Monday evening that six individuals, including Bloomer and Clifford Chance lawyer Chris Morvillo, were still missing. When contacted by CNBC, Clifford Chance declined to provide any comment.

Since 2016, Bloomer has been the non-executive chair of Morgan Stanley International, the London-based branch of the investment banking giant, and also serves as the chair of insurance firm Hiscox.

The group chief executive officer of Hiscox, Aki Hussain, stated that Bloomer and his wife Judy were among the missing individuals.

"Hussain expressed deep shock and sadness over the tragic event in a statement, while a Morgan Stanley spokesperson said their thoughts are with the affected individuals, especially the Bloomer family, as they await further updates on the situation."

On Tuesday, search and rescue efforts continued as Mike Lynch, a British tech entrepreneur, and his 18-year-old daughter Hannah remained missing.

On Monday at 4 a.m. local time, the 56-metre sailing boat "Bayesian" was hit by a violent storm while carrying 10 crew members and 12 passengers on board. The anchored vessel capsized near the port of Porticello, with witnesses reporting that the boat descended rapidly after its mast broke.

The ship's cook, who was Lynch's wife, was confirmed by the Italian coastguard to have died. Angela Bacares, Lynch's wife, was among the 15 people who were rescued.

On Monday, Renato Schifani, the president of Sicily, visited the children's hospital in Palermo to meet with the British one-year-old girl and her parents who were rescued from the ship.

Schifani stated in a translation that her thoughts are with all those involved and their families, but today we are also here to acknowledge the importance of the health workers and Civil Protection volunteers in our community's solidarity and commitment.

It is believed that those who supported the move were employees and associates of Lynch, the 59-year-old founder of enterprise software firm Autonomy.

Hewlett Packard accused Lynch of inflating Autonomy's value in an $11 billion sale, leading to a protracted legal battle.

Last year, he was extradited from Britain to the U.S. to stand trial over HP allegations. In June, Lynch was acquitted of fraud charges after a three-month trial.
