17 October 1991
The proposed launch of the United Front was threatened when the Azanian People's Organisation (AZAPO) denounced fourteen of the more than seventy-five organisations represented at a meeting in Durban to initiate the creation of a united front in negotiations with the South African government. AZAPO accused the implicated organisations of either having participated in apartheid structures or for their racial make-up. The move of AZAPO caused the withdrawal of the Democratic Party and angered other organisations. On 20 October the African National Congress (ANC) and the Pan-Africanist Congress (PAC) barred AZAPO from the committee convening the conference, but invited it to take part in the conference itself - an invitation which AZAPO declined.
