delegates and two advisers from each party. However, the bulk of the MPNF's work was done in its Negotiating Council, which contained two delegates and two advisers from each party, and which was almost continuously in session between April and November. It was in the council that proposals were developed and compromises thrashed out before being sent for formal approval in the higher tiers of the body. The issues before the Negotiating Council were almost identical to those discussed at CODESA and the MPNF built on the latter's work. However, in a new innovation, the Negotiating Council at the end of April resolved to appoint seven technical committees, staffed mostly by lawyers and other experts, to assist in formulating detailed proposals on specific matters. As a result of agreements reached earlier by the Gender Advisory Committee of CODESA, at least one party delegate at each level of the MPNF had to be a woman. In principle, the parties to the forum participated on an equal basis, irrespective of the size of their support base, with decisions taken by consensus. In practice, however, the ANC and NP developed a doctrine known as "sufficient consensus", which usually deemed bilateral ANC–NP agreement (sometimes reached in external or informal forums) "sufficient", regardless of any protests from minority parties. As a result, the MPNF was still more dominated by the interests of the ANC and NP than CODESA had been. Assassination of Chris Hani: April 1993 On 10 April 1993, a white extremist assassinated senior SACP and ANC leader Chris Hani outside Hani's home in Boksburg, Gauteng. Hani was extremely popular with the militant urban youth, a constituency whose commitment to a peaceful settlement was already tenuous, and his murder was potentially incendiary. However, Mandela's plea for calm, broadcast on national television, is viewed as having increased the status and credibility of the ANC, both internationally and among domestic moderates. Thus, somewhat paradoxically, the incident helped accelerate consensus between the ANC and the government, and on 3 June the parties announced a date for democratic elections, to be held in April the next year. Storming of the World Trade Centre: June 1993 On 25 June 1993, MPNF negotiations were dramatically interrupted when their venue was stormed by the right-wing Afrikaner Weerstandsbeweging (AWB), whose supporters crashed through the glass front of the building in an armoured car and briefly took over the negotiations chamber.
