The Duke’s role as Britain’s roving business ambassador has been examined extensively by the British media this week, and in the latest development it has emerged he lobbied an MP to help British business in a former Soviet republic accused of torturing protesters.
Andrew met Conservative MP Mark Field, chairman of the all-party parliamentary group on Azerbaijan, on Monday to highlight the “tremendous opportunities” in the central Asian autocracy.
Human rights organisation Amnesty International has condemned the oil-rich state for its violence towards civil society activists.
Despite receiving the backing of Prime Minister David Cameron and Chancellor George Osborne, the Duke has been dogged by accusations of a lack of judgment about his friendship with US billionaire Jeffrey Epstein, a convicted sex offender.
Further details about his dealings with Epstein were revealed when it was reported the American landed his private jet at an RAF fighter base during a visit to Sandringham in 2000.
Other reports have claimed that the Queen, despite giving her backing to her son according to royal sources quoted in the press, has met Andrew to discuss recent events.
The Duke appeared relaxed as he arrived at a science and engineering fair for young students, The Big Bang event, in London’s Docklands.
The Duke launched the Royal Navy’s engineering app that uses maritime- themed games to encourage students to think about a career in the service.
