South African ruling party chief Jacob Zuma heads to court on Monday for the start of a long-awaited trial which his lawyers will seek to have thrown out of court.
It is the second time the state has attempted to prosecute Mr Zuma for corruption.
A judge described the prosecution's last bid, in 2006, as a disaster.
It's thought ongoing legal challenges relating to the investigation could delay the trial until after general elections in 2009, when Jacob Zuma is tipped to become president as the candidate for the majority African National Congress.
He faces a total of 16 charges ranging from money-laundering to racketeering, legal experts believe a trial could drag on for months.
