British tech entrepreneur Mike Lynch is missing after a luxury yacht sank off the coast of Sicily, BBC News has confirmed.

Sources close to the matter have also confirmed that his wife, Angela Bacares, has been rescued. 

British businessman Mike Lynch, who is reportedly missing after the luxury yacht sank off the coast of Sicily, made his fortune in the IT industry.

Lynch co-founded software company Autonomy in Cambridge in 1996, which expanded rapidly to become one of the UK's leading tech firms.

His company's success led it to be being sold to computing giant Hewlett-Packard for $11bn (£8.6bn) in 2011 - a deal in which Lynch made £500m ($647m).

But the acquisition soon unravelled, as questions were asked about the enormous price tag.

Just a year later, HP wrote down the value of Autonomy to $8.8bn, saying Lynch had exaggerated its value.

Years of legal battles followed, which culminated in US prosecutors bringing charges against Lynch in 2018.

Prosecutors accused him of inflating the value of the firm by using backdated agreements to mislead about the company's sales, said he had concealed the firm's loss-making business reselling hardware, and also accused him of intimidating or paying off people who raised concerns.

But he was eventually extradited to the US in 2022 to face trial - a process which culminated in June with his acquittal.

In an interview with the BBC earlier this month, Lynch said "the reason I'm sitting here, let's be honest, is not only because I was innocent... but because I had enough money not to be swept away by a process that's set up to sweep you away".

BBC Verify has been looking at corporate records of the Bayesian and have found that the luxury yacht is tied to the wife of Mike Lynch, a British businessman who is reportedly among the missing.

According to Equasis, a maritime data service, the Bayesian is owned by Revtom, a firm registered in the Isle of Man.

The company's latest annual statement was filed in April with the Isle of Man’s Companies Registry. In the statement, Angela Bacares is named as the sole legal owner, with an address registered in London.

Bacares was among the 15 people rescued, a source tells the AFP news agency.
