The Economic Freedom Fighters (EFF) believes President Cyril Ramaphosa's move to possibly suspend Public Protector Busisiwe Mkhwebane is dictatorial and fear driven.
The party has been steadfast advocates for Mkhwebane in the past, and it held no punches in speaking against any move to suspend her.
The EFF labelled the possible suspension as another attempt to destroy an African woman.
"The letter demanding that Mkhwebane pleads her case to not be suspended is a veiled threat, and an effective removal of the Public Protector before a democratic institution can appraise itself on her performance, and whether she is capable of occupying that office.
"It is an implementation of the factional and undemocratic step-aside policy of his (Ramaphosa's) ruling party at the level of the state, which finds people guilty until proven innocent."
Ramaphosa wrote to Mkhwebane asking her to give reasons why he should not suspend her pending the finalisation of the parliamentary impeachment proceedings investigating her fitness to hold office.
The president gave her 10 days to respond.
Ramaphosa has moved swiftly on the legislative prerogative, which allows him to suspend Mkhwebane while she faces an inquiry led by Parliament.
Earlier, News24 reported that National Assembly Speaker Nosiviwe Mapisa-Nqakula had written to Ramaphosa, informing him that the impeachment process against Mkhwebane would continue.
The EFF said Parliament's Section 194 Committee, which is dealing with the impeachment process, should be allowed time to do its work.
The party said Ramaphosa was conflicted in matters related to Mkhwebane, adding that her suspension was aimed at stripping her office of its powers.
"Busisiwe Mkhwebane has been unwavering in her mandate to hold those in power accountable, and she has done so indiscriminately, implicating Ramaphosa and his allies. To suspend her is, therefore, a measure to strip the Office of the Public Protector of its teeth. It is premature, rushed and leads us to conclude that it is a decision taken out of fear, rather than being based on rationality," the EFF said.
"His desire for power makes him destructive. He is willing to destroy institutions, create vacancies and operate like a dictator, to ensure that anyone who dares to oppose him is removed," it continued.
Earlier, Mkhwebane said she was seeking legal advice on the president's notice to suspend her.
She previously indicated that she would fight efforts to place her on suspension while her impeachment proceedings continued.
