He's worked with almost every US President since Gerald Ford. Paul Manafort, a political lobbyist and Trump's former campaign manager, is under house arrest charged with money laundering and fraud, his lavish lifestyle of luxurious mansions, fast cars and antique rugs laid bare by the FBI. Mark Coles profiles this powerbroker who some say may become a key witness for the investigation into Russia's alleged meddling in the US election.
