Andrew Mountbatten-Windsor's time as trade envoy should be investigated for possible corruption, a former business secretary said.
Files released by the US department of Justice appear to show the former prince forwarded UK government documents and other commercial information to the convicted sex offender Jeffrey Epstein.
Speaking about reports of Andrew leaking sensitive information about the Royal Bank of Scotland (RBS) and Aston Martin while trade envoy, Sir Vince Cable, said his behaviour was "totally unacceptable".
Andrew has always consistently and strenuously denied any wrongdoing.
Sir Vince, who was secretary of state for business and trade for some of the former duke's time as trade envoy, said: "We need a police or DPP [director of public prosecutions] check on whether criminal corruption took place and a government investigation into how this was allowed to happen".
