The yacht trip was to celebrate Lynch's legal win in the wake of serious charges, including fraud.

Regarding the yacht sinking, Lin Ronald said it was "a very unusual very rapid incident which is very sad for all involved". The luxury yacht was struck by an unexpectedly violent storm and sank off Sicily early on Monday (local time). The British-flagged Bayesian, a 56-metre-long sailboat, was carrying 22 people and was anchored just off shore near the port of Porticello when it was hit by ferocious weather, the Italian coast guard said in a statement.

Eyewitnesses said the yacht vanished quickly beneath the waves shortly before dawn. Fifteen people escaped before it went down, including Lynch's wife, Angela Bacares, who owned the boat, and a one-year-old girl. The names of the dead and missing were not immediately .
