Two Rulers, One Ballot: The Negeri Sembilan Crisis

A crowd in Kuala Pilah shouted the ancient royal salute “Daulat Tuanku” for Yang di-Pertuan Besar Muhriz Munawir after Friday prayers. Hours earlier and forty kilometres away, the same cry rang out for his cousin, Nadzaruddin Ja’afar, as he arrived at a traditional chieftain’s residence. The rival scenes capture a succession fight that has plunged Negeri Sembilan into a constitutional crisis on the eve of its state election.

The dispute pits two heirs of South-east Asia’s oldest surviving elective monarchy against one another. In April, the four hereditary chieftains – the Undang – attempted to depose Muhriz and, on 5 June, proclaimed Nadzaruddin as the new ruler. The federal government, backed by the Attorney-General, continues to recognise Muhriz as the legitimate Yang di-Pertuan Besar, while the Pakatan Harapan-led state government has also publicly sided with him. The stand-off has moved from the palace to the courts, with legal challenges over the appointment of customary chiefs and the interpretation of Adat Perpatih, the Minangkabau-derived customary law unique to the state.

Because roughly 20 to 25 of the 36 state assembly seats lie within the territories of the four Undang, the crisis is set to shape the election. The ruling PH coalition is leaning on its economic record, but analysts say the monarchy issue will dominate in Malay-majority and Undang-related constituencies. The opposition bloc of Barisan Nasional (BN) and Perikatan Nasional (PN) is using the rift to accuse the PH government of interfering in traditional affairs. The outcome could therefore decide whether Anwar Ibrahim’s coalition retains control of the state assembly.

How the Royal Feud is Reshaping the Election Calculus

How the Undang’s Revolt Split the Adat Perpatih Vote

The crisis hinges on a clash between two readings of customary law. Supporters of Muhriz argue that he is the lawful ruler under the existing constitutional framework, and that any removal would require death, illness or mental incapacity – none of which applies. Supporters of Nadzaruddin insist the Undang, as guardians of Adat Perpatih, have the right to elect the ruler and that the federal government’s interference violates centuries-old convention.

The partisan overlay is stark. A vote for PH in rural Malay seats is increasingly seen by some as a vote for Muhriz and against the Undang’s authority. BN and PN, despite competing nationally, have formed an electoral pact and are portraying themselves as the only coalition that can resolve the succession “from within the Adat”, as political scientist Tricia Yeoh puts it. The Undang of Johol publicly urged a Malay-led government without naming a party, a call widely understood as a coded endorsement of the BN-PN pact. While PH can still count on Muhriz loyalists and urban mixed seats, the Undang’s influence may swing conservative Malay constituencies away from the ruling coalition – a potentially decisive shift in a state where rural seats carry heavy weight.

The Risks of Anwar and Aminuddin’s Public Bet

Prime Minister Anwar and Menteri Besar Aminuddin Harun have explicitly backed Muhriz as the legitimate ruler, framing their position as one of legal correctness. But in the highly symbolic universe of Adat Perpatih, taking sides is itself a transgression, according to critics: the executive, they say, has no business adjudicating a matter reserved for the Undang. Several voters interviewed by The Straits Times described the move as bias that disrespected tradition, and for some it was the turning point that eroded long-held support for PH. BN-PN have weaponised this perception, accusing the state government of meddling in the luaks’ internal affairs. Even if the PH leadership’s stance may appeal to modernists and Muhriz supporters, it risks alienating a broader traditionalist Malay electorate that values procedural purity over outcome.

A Generation Gap and the Limits of Custom

The dispute resonates unevenly across age groups. Older voters like 70-year-old Che Rus Husin and 68-year-old Muhamad Kamel Yassin feel a visceral duty to defend their ruler, while younger people are less engaged. The 22-year-old son of a Muhriz supporter “has little interest in the constitutional crisis”, and a healthcare worker in Jelebu told the press the dispute “does not affect [his] daily life”. Nevertheless, the crisis has revived a dormant sense of clan identity among some middle-aged voters who returned to their ancestral districts. For them, the election is no longer just about infrastructure and jobs; it is a test of the government’s commitment to protect a cultural heritage enshrined in law. This emotional dimension makes the vote harder to predict, as it cuts across conventional programme-based assessments.

What the Dispute Means for Voters, Parties and the State

Voters in Undang territories should expect the election narrative to intensify around Adat Perpatih, with BN-PN framing a vote for them as a restoration of traditional order. Those weighing the choice will need to separate legal arguments from political opportunism: the federal Attorney-General’s advice and court proceedings will matter for the succession’s legality, while the Undang’s call for a Malay-led government is a transparent electoral message. Urban and mixed-seat voters are less likely to be swayed by the royal issue and will probably decide based on PH’s state-level performance in financial management and investment.

For PH and its leadership, the crisis is a stress test of the coalition’s hold on rural Malay support. Losing even a handful of Undang-influenced seats could reduce or erase PH’s assembly majority. The party must decide whether to double down on its legal-constitutional line or signal openness to customary mediation without appearing inconsistent. Its choice will shape not only the 2026 state result but also future relations with the traditional elite across Malaysia.

Risk & Opportunity Assessment

Commercial RiskMediumA change in state government or prolonged instability could delay business licences and approvals; there are already allegations that an Undang issued mining licences without proper authority, indicating that the dispute has a direct commercial spillover in the mining sector.
Competitive RiskMediumBN-PN have formed a pact to exploit the royal crisis, directly challenging PH’s control of the state assembly. A shift in power would alter infrastructure and investment priorities, affecting firms that have aligned with the current administration.
Regulatory RiskHighThe federal government’s decision to recognise only Muhriz is being challenged in court and by the Undang. If the courts force a reinterpretation of Adat Perpatih or the constitutional role of the Undang, the entire electoral process of the monarchy could be upended, creating legal uncertainty for any executive decisions made under the disputed ruler.
Reputation RiskCriticalPrime Minister Anwar and Menteri Besar Aminuddin are being accused of meddling in customary affairs, and one voter explicitly said his support for PH unravelled because of Aminuddin’s bias. If the perception spreads that PH disrespected Adat Perpatih, the coalition’s credibility in the conservative Malay heartland will suffer, potentially lasting beyond this election.
Technology DisruptionLowNo technological disruption is evident in this political and customary dispute.
Commercial OpportunityMediumShould BN-PN win, firms connected to the new administration could gain preferential access to state contracts and natural resource deals, particularly in districts where Undang support has been pivotal. Conversely, a PH victory would cement the status quo for investors that have prospered under Aminuddin’s financial management.
