The group subsequently elected Mangoma as their president on 20 October that year.[1] As president of the bloc, Mangoma ran as their presidential candidate during the 2018 General Election campaign. As he was running for the presidency, Mangoma could not run for re-election to the House of Assembly for his constituency.
