Sovcomflot-owned tanker company Novoship is heading to court again in a $91m case involving an alleged sex tape of a US oil tycoon.

It is suing Daniel Hall, a senior executive at Burford Capital, in London's high court, accusing him of unlawfully trading confidential documents for the footage, the Financial Times reported.

Hall, co-head of Burford’s global corporate intelligence, asset tracing and enforcement business, is alleged to have supplied “sensitive” documents obtained while working for Novoship.
