The leader most closely associated with Desmond Tutu and FW de Klerk is 3. Nelson Mandela. Tutu and De Klerk were both prominent features in South Africa during the period of apartheid. In fact, De Klerk was the leader of South Africa that won a Nobel Peace Prize with Nelson Mandela for ending apartheid and opening elections to native South Africans rather than simply white Afrikaaners in 1994.
Do you know the context?
I suppose the quotation is stressing that the writer has put a lot of effort into getting their argument/grievances heard by the parliament, and that said parliament is 'tyrannical', implying that it rules without concern for the people or accountability to them. It seems that the quote may be a way of justifying some later action, essentially saying; 'we've tried and failed to do this in the proper way, so now we must be more forceful'.
