Despite the hashtag #DontFillUpOrlandoStadium, the ANC managed to fill to capacity the 40 000-seat Orlando Stadium in Soweto.
Black people must benefit from the economic resources of the country, President Jacob Zuma said in his very last January 8 statement.
The ANC is imploding and has to "bus in supporters" from Mpumalanga and KZN to hold a successful rally in Gauteng, EFF leader Julius Malema said.
"I am thankful to God that my party is turning 105 today. I am a member in good standing and this is our party and no other."
The Orlando Stadium was already packed to capacity just after 10 am, with many supporters still hoping to get in for the ANC's birthday bash.
ANC secretary general Gwede Mantashe is confident that 2017 will be a good year for the ruling party, as it heads toward its elective conference.
Despite the pouring rain, hundreds of people have already begun streaming into the Orlando Stadium in Soweto.
