South Africa's former President, Jacob Zuma, is giving evidence this week at a commission set up to investigate corruption allegations during his time in office.
The inquiry takes its name from an academic term, "state capture", that has become a buzzword - shorthand for the multiple scandals that plagued the Zuma administration and eventually brought it down.

State capture describes a form of corruption in which businesses and politicians conspire to influence a country's decision-making process to advance their own interests. As most democracies have laws to make sure this does not happen, state capture also involves weakening those laws, and neutralising any agencies that enforce them.
