A large crowd has begun gathering outside the Sisa Dukashe Stadium in Mdantsane near East London to await the arrival of ANC President Jacob Zuma, the SABC reported.

Zuma is scheduled to attend the Workers' Day rally there, the national broadcaster said.

Earlier it was reported by the Congress of SA Trade Unions that more than two thousand buses were expected to transport people from various places to the stadium, the SABC added.

Cosatu secretary general Zwelinzima Vavi and the SACP's Blade Nzimande are also expected to attend the rally.
