Lobby group the National Constitutional Assembly (NCA) has vowed to frustrate any talks on constitutional reform between the ruling ZANU-PF party and the opposition. It argues that only Zimbabweans - not political parties – have the right to decide on the matter. NCA chairman Lovemore Madhuku told IRIN he would consider negotiations on constitutional reforms between the two parties an "illegitimate process", even though the opposition Movement for Democratic Change (MDC) had its roots in the NCA and the labour movement.
