"As the leadership of the NFP in Gauteng, we urge our loyal members of the organisation to desist from participating in protest marches that are clearly aimed at undermining the constitution of the Republic, which gives the President of the country full powers to appoint and fire ministers," said provincial secretary Sabelo Dlamini.
"While we won’t stop any person from exercising their right to protest, we discourage wearing of party regalia. Those that would be found in defiant of this order will be dealt with accordingly...we will use all internal disciplinary mechanisms to deal with them."
Opposition parties such as the Economic Freedom (EFF), Democratic Alliance (DA), the United Democratic Movement (UDM), Inkatha Freedom Party (IFP), United Christian Democratic Party (UCDP), the Congress of the People (Cope) and the African People's Convention (APC) have organised a national march for Wednesday in Pretoria to call for President Jacob Zuma to resign.
Thousands of people are expected to take part and march to the Union Buildings. Wednesday is Zuma's 75th birthday, with celebrations set to take place in Kliptown, Soweto.
Dlamini said the march was nothing "but a coming together of groupings to defend their wealth accumulated through back door means".
"We caution our members against the tendency of participating in something that they don’t real understand and in our view, something that will not benefit the organisation. We cannot be part of the threat against the Constitution. If President Zuma has in anyway trampled upon the Constitution, then the onus is upon his organisation to take action against him," Dlamini said.
"We say this because so many things have happened in our country, but no marches have been held and the moment President Zuma talks about the economic transformation agenda, he becomes the enemy number one."
