The uMkhonto weSizwe (MK) Party has taken decisive action against two prominent members, expelling Duduzile Zuma-Sambudla and Nhlamulo Ndhlela with immediate effect. The move, announced on 18 June 2026, underscores deepening internal tensions within the party founded by former president Jacob Zuma.

Party secretary-general Sibonelo Nomvalo stated that the expulsions followed careful consideration of actions and statements that conflicted with the organisation’s values, discipline and constitutional principles. Both individuals had been suspended earlier in the year for misconduct, and recent developments rendered their continued membership untenable.

Background to the Expulsions

The MK Party emerged as a significant force in South African politics following the 2024 national elections, drawing support from those disillusioned with the African National Congress. Jacob Zuma, the party’s president, positioned it as a vehicle for radical economic transformation and accountability. However, rapid growth has brought challenges in maintaining unity.

Duduzile Zuma-Sambudla, daughter of the party leader, and Nhlamulo Ndhlela, a former national spokesperson and MP, played visible roles in the party’s early development. Their expulsions mark a notable shift, highlighting the party’s determination to enforce discipline even at the highest levels.

Reasons Cited by the Party

According to official statements, the pair engaged in conduct that promoted factional narratives, challenged leadership decisions publicly, and exposed internal matters through social media and at party events. These activities were said to have caused confusion among members and fuelled divisions.

The party emphasised that the expulsions were not taken lightly. Invoking constitutional powers, the leadership determined that the actions had become fundamentally incompatible with organisational interests. Membership rights, privileges and authority were terminated immediately for both individuals.

Reactions and Legal Challenges

Nhlamulo Ndhlela has indicated that he and Duduzile Zuma-Sambudla are instructing lawyers to approach the high court to challenge the expulsions. This development suggests the matter may extend beyond internal party processes into the judicial arena.

Supporters of the expelled members have expressed surprise and disappointment, viewing the decision as a departure from the party’s founding ethos of inclusivity. Critics within the party, however, argue that firm action was necessary to preserve cohesion ahead of upcoming electoral contests.

Implications for Party Unity

The expulsions occur at a critical juncture for the MK Party as it seeks to consolidate its position in national and provincial politics. Internal divisions risk alienating voters who were attracted by the promise of a disciplined alternative to established parties.

Observers note that the leadership’s willingness to act against high-profile figures, including the daughter of the party president, signals a commitment to institutional norms over personal ties. Whether this strengthens or fractures the movement remains to be seen.

Broader Political Context

South Africa’s political landscape continues to evolve rapidly following the formation of the Government of National Unity after the 2024 elections. Smaller parties like the MK Party face pressure to demonstrate organisational maturity if they are to remain relevant.

The episode also raises questions about succession and influence within parties built around charismatic leaders. As Jacob Zuma’s movement navigates these challenges, the handling of dissent will shape its long-term trajectory.

Public and Media Response

Media coverage has been extensive, with outlets across the country reporting on the developments. Social media platforms have seen vigorous debate, with some users praising the party for enforcing accountability and others decrying the move as heavy-handed.

Analysts suggest that the expulsions could influence voter perceptions ahead of local government elections, particularly in KwaZulu-Natal where the party has significant support. Clear communication from leadership will be essential to mitigate any negative fallout.

Future Outlook

The MK Party has stated its intention to focus on unity and discipline moving forward. Party structures are expected to review internal processes to prevent similar situations from arising.

For now, the expulsions serve as a stark reminder that political movements, even those founded on revolutionary ideals, must balance loyalty with organisational integrity. The coming months will test whether the MK Party can emerge stronger from this episode or whether further fractures lie ahead.
