An outspoken member of South Africa’s African National Congress (ANC) party has been charged with ill-discipline for speaking out against President Jacob Zuma.
MP Makhosi Khoza has repeatedly called for Mr Zuma to resign. Last week, she said he was a disgrace.
She has received death threats warning her to stop pushing for a secret ballot when MPs vote on Mr Zuma next month.
Parliament and the police decided to provide security for her.
Last week, the ANC said she had crossed the line and must face disciplinary action for speaking out against the president.
The ANC in her home province of KwaZulu-Natal called her comments a “blatant betrayal of the core values” of the party.
Ms Khoza, 47, has also been a critic of corruption within the ANC.
Mr Zuma has faced numerous allegations of corruption, all of which he denies.
The National Assembly is expected to vote on a motion of no-confidence in him on 8 August.
Last week Ms Khoza received a death threat saying she had 21 days left to live.
She called Mr Zuma a disgrace at a ceremony to mark Nelson Mandela’s birthday on 18 July.
She was addressing civil society groups, unions and business leaders pressing for Mr Zuma’s removal in next month’s no-confidence vote.
There is no suggestion that he is connected to the death threats.
Jacob Zuma has survived several previous votes of no-confidence.
The constitutional court ruled in June that parliament had the right to conduct a secret ballot, but the speaker has yet to announce a decision on the issue.
Mr Zuma is due to stand down as ANC president in December and whoever takes over would lead the party into the 2019 elections.
