In 2005 he was the first reporter to film Iran's secret nuclear sites, making an hour-long documentary which was shown around the world. For four years Paul had his own series on BBC One, Kenyon Confronts which used secret filming to expose corruption in areas as diverse as horse-racing, the Catholic Church and immigration. At its peak it was the most watched current affairs programme on the BBC. Paul currently works on Panorama and he became friends with Justice Amin while researching a two-part story on African migrants for the programme in 2007.
