Zwelinzima Vavi - Standing up to the corrupt and the powerful.
The former child labourer now leads Africa's largest trade union movement, the Congress of South African Trade Unions (COSATU).
He has been called a reckless ultra-leftist, a loose cannon and an irritation to the powerful white and black business elites.
But for the millions of poor and unemployed South Africans, Vavi remains the working class hero who is not shy to hold politicians to account.
His virulent tirades against corruption within the ruling ANC make him one of the few moral voices trying to change things from within the tripartite alliance.
