There is a balanced view on Mmusi Maimane's Zambian 'adventure' in today's Business Day (May 29) by ONKGOPOTSE JJ TABANE headed "Conspiracy of silence blunts Africa Month celebrations". This reduces Yonela Diko's diatribe to pro African National Congress rhetoric. 
Whereas Diko focuses much on events elsewhere, Tabane writes on lack of African support for MM's action from political entities and puts the spotlight on the Southern African Partnership for Democratic Change (SAPDC), a network of opposition politicians formed to share expertise and advice on governance. Members are Lesotho’s All Basotho Convention, Namibia’s Rally for Democracy, Zimbabwe’s Movement for Democratic Change, South Africa’s DA, Tanzania’s Civic United Front, Zambia’s Movement for Multiparty Democracy, Angola’s Convergencia Ampla de Salvacao de Angola-Coigacao Eleitoral and Swaziland’s United Democratic Movement. MM went to Zambia as SAPDC chairman. That fact takes the stuffing out of Diko's argument.
