31 December 1989
On 31 December 1989, ex-mutineers in exile considered resigning from the African National Congress (ANC). This came after the suppression of political and cultural renewal by the ANC and the banishment of nine members of the ANC at Dakawa and Mazimbu in Tanzania on 28 December 1989. The banishment came after meetings of ANC communities at Dakawa and Mazimbu that were addressed by Chris Hani and Stanley Mabizela on 24 December 1989. In one of the meetings at Dakawa, Tanzanian Field Force had to be called in to stabilise the situation as the meeting turned chaotic. According to reports the whole of the ANC in Tanzania was filled with tension as some members were unhappy about the suppression of political and cultural renewal. Early in 1990, a group of ex-uMkhonto weSizwe(MK) cadres mysteriously returned to South Africa.
