Antony Barnett has joined the reporting team for Dispatches after 10 years on The Observer.
Barnett's work on The Observer included the paper's exposé of New Labour lobbyists in the so-called Lobbygate scandal and his revelations over the Hinduja brothers which sparked the cashfor- passports affairs that led to the resignation of Peter Mandelson.
His recent Dispatches film on gambling, Labour's Gambling Addiction, exposed the backroom deals and secret meetings used to bring in the Government's Gambling Act.
Barnett began his journalistic career working for specialist business magazines before freelancing for the BBC, The Guardian and The Times. He became The Observer's industrial correspondent in 1996 and its public affairs editor in 2000. In 2005 he was made The Observer's investigations editor.
Dispatches editor Kevin Sutcliffe said the appointment was made to strengthen the programme's in-house reporting team, on the back of an increased run of Dispatches to 40 broadcasts.
