"It [the provincial executive committee] characterised the formation as counter-revolutionary, primarily aimed at undermining the authority of the ANC as well as seeking to sow divisions within the organisation in the build up to the Mangaung congress," provincial deputy chairman Simon Molefe told reporters in Johannesburg.

"This formation is no different to how [the Congress of the People] came into existence, primarily informed by a reluctance to accept outcomes of internal ANC processes."

Molefe said the PEC was concerned by the ANCYL's national executive committee's silence on the group and urged it to publicly announce where it stood.

Friends of the Youth League was established shortly after former ANCYL president Julius Malema was expelled from the ANC.

It organises events around the country at which Malema can address supporters.

Molefe said the Gauteng ANCYL would take disciplinary action against any of it members or structures within the province who associated themselves with the group.

"The unity and cohesion of the ANC is paramount, and no individuals should be allowed to undermine such, especially those that are no longer members of the organisation," said Molefe.
