Seasoned journalist and political analyst Karima Brown predicts that President Zuma's critics within the ANC will face scrutiny for their action or inaction during today's vote of no confidence debate.
Members of Parliament (MPS) can either vote yes, vote no, or abstain.
Brown says vocal ANC MPs, such as chief whip Jackson Mthembu will have to somehow pass the bar of credibility.
She says the public will be watching Zuma's critics closely, and they will have to manage the public perception if they are seen as meek MPs who take no action.

Meanwhile, EFF leader Julius Malema said the motion was a bad idea as it would unite opposing ANC factions.
