He worked for the New York Herald Tribune in Paris, The Observer, The Sunday Times and BBC Television, initially as Barrie Sturt-Penrose.
In December 1979, John Cairncross – who had secretly admitted to an MI6 interrogator that he had spied for the Soviets – was approached by Penrose and made a full confession to the journalist.
In the course of his reporting and subsequent authorship of the book Stalin's Gold, Penrose claimed salvage expert Keith Jessop was "unprincipled and devious", had secured the contract through nefarious means including bribery, and that the divers routinely messed with and desecrated the bodies entombed in the wreck during the dive.
Taken to tribunal by Keith Jessop over those claims, Penrose's words were judged libellous and all copies of Stalin's Gold were ordered pulped.
