Former president Jacob Zuma has pleaded not guilty to corruption charges on Wednesday.

Zuma and the French arms company Thales are accused of corruption, racketeering, and money laundering linked to the arms deal.

Thales also pleaded not guilty to all charges.

The former president has also applied for a special plea to have state prosecutor Advocate Billy Downer removed.

He claims that his prosecution is political and Downer is biased.
