Premise: Prosecutors in South Africa are set to announce whether they will drop corruption charges against African National Congress leader Jacob Zuma. Mr Zuma is widely expected to become the country's next president after elections later this month. He is accused of graft, racketeering and money-laundering in connection with an arms deal signed with western companies in 1999. The 66-year-old denies the charges and says they are part of a political plot. Mr Zuma was first charged in 2005, but has yet to face trial.
Hypothesis: Jacob was originally charged in 2002.
