The ANC has warned delegates against wearing T-shirts that that could fuel tensions during the national congress in Polokwane this weekend.
In a statement issued after an ANC special national executive committee meeting yesterday, the party said the conference will adopt rules at the opening to prohibit the display or distribution of material that is divisive or that might promote factionalism.
"Conference participants may, therefore, not wear T-shirts or other clothing featuring any of the candidates for election to the NEC. This prohibition includes official ANC T-shirts produced for past election campaigns," said ANC spokesman Smuts Ngonyama.
He said only accredited delegates will be allowed access to the conference precinct and immediate surroundings. This prohibition is meant to ensure that delegates are able to exercise their rights and responsibilities without interference.
The NEC hoped that delegates will unite and strengthen the ANC for the next five years.
Delegates are requested to adopt policies and programmes that will make a "real difference to the lives of all South Africans, particularly the poor".
"In this conference, delegates will be required to faithfully reflect the views of the general membership of the ANC," said Ngonyama.
He said delegates will also need to demonstrate discipline and commitment to the task that the structures who mandated them expect.
"It is important that participants at conference, whether delegates, observers or guests, desist from any conduct that may be divisive, disruptive or otherwise deviate from the democratic traditions of the movement," Ngonyama added.
The NEC meeting considered the political, organisational and financial reports to be presented to the conference.
And the programme, rules and the logistical arrangements.
The NEC also reviewed secretary-general Kgalema Motlanthe's organisational report in detail.
The report deals with the work and state of the organisation over the last five years.
It also provides a critical analysis of the achievements, shortcomings, strengths and weaknesses since the organisation's 51st national conference in Stellenbosch in 2002.
Ngonyama said the report is expected, among others, to form the basis for commission discussions on organisational renewal, constitutional amendments and the ANC programme of action to 2012.
Ngonyama said the NEC is confident that all political preparations and logistical arrangements are in place and envisaged that the conference will be successful.
The NEC also received a report on the credentials of delegates to conference and was informed that almost all of the 4075 voting delegates have now registered.
A total of 450 non-voting ANC delegates, 135 observers from allied organisations, and 360 local and international guests are also expected to attend the conference. It will be held at the University of Limpopo from December 16-20.
The ANC will have about 200 support staff and over 1000 service providers.
Nearly 700 journalists will attend.
