JOHANNESBURG - Seventy years on, and the Freedom Charter's toughest battles are still being fought.

READ: 70 years of the Freedom Charter

The ANC's First Deputy Secretary General, Nomvula Mokonyane, says the most stubborn clauses are those concerning wealth sharing and the contentious land issue. 

She made the comments during the 70th-anniversary event of the Freedom Charter.

On that historic day in Kliptown, some 3,000 delegates from all political formations united to forge the Charter's powerful core principle: "South Africa belongs to all who live in it."
