ANC pledges to ensure the country’s black majority secures a bigger stake in the economy and do more to create jobs, as it seeks to claw back support.
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 Youth League should mobilise young people and prepare their "political education into the mother body", ANC President Jacob Zuma told supporters.
"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.
