During the 1960s, the party split into Soviet-allied (Kena, Malefane, Mtji, and Ms Hoohlo) and Chinese-allied (Motloholoa, T. Leanya, and T. Nqojane) factions. In the 1970 election, its two Moscow-allied candidates at Thaba Chitja (Kena) and Tsoelike (Malefane) received 25 and 18 votes respectively. The party was officially banned in February 1970, but went underground and continued its activities. After the 1986 coup, its leader, Sefali Malefane, a university lecturer in Economics, was made a minister in Major-General Justin Lekhanya's regime. The party was made legal again in 1991.[2]
After the fall of apartheid rule in neighbouring South Africa, the party advocated union with South Africa.[3]
The party ceased the publication of its newspaper, Mafube, in 1997.[4]
