The stability of Malaysia's Perikatan Nasional (PN) coalition faces a critical test as internal divisions between its two largest components—PAS and Bersatu—threaten to fracture the bloc. Caught in the middle of this standoff are two smaller coalition partners, Gerakan and the Malaysian Islamic Party's splinter faction known as MIPP, both of which have so far declined to publicly declare their allegiance despite mounting pressure to do so. Their silence reflects a broader dilemma confronting political players across the peninsula: the party machinery and electoral calculations that kept them invested in PN's original promise are now being severely tested by the very tensions that have emerged within the coalition itself.

The PN alliance, formed in 2020 as an alternative to the Pakatan Harapan government, represented a significant realignment in Malaysian politics. It brought together Bersatu—then led by Prime Minister Muhyiddin Yassin—alongside PAS and several other parties in what was presented as a Malay-Muslim majority coalition. For smaller partners like Gerakan and MIPP, joining or remaining within PN offered a pathway to parliamentary influence and the possibility of cabinet positions or state-level prominence that might have been difficult to achieve independently. Yet the internal cohesion that held the coalition together in its early years has visibly deteriorated, particularly as Bersatu and PAS have clashed over leadership, ministerial distribution, and ideological direction.

Bersatu's struggle to maintain its position within PN has become increasingly precarious in recent months. The party, which once controlled the prime ministerial office, now faces questions about its relevance and influence within a coalition increasingly dominated by PAS's organizational strength and electoral machinery. PAS, as the more established Islamist party with deeper roots in the Malay heartland, has sought to consolidate its leverage within PN, creating an asymmetry that threatens to marginalize Bersatu further. For Bersatu, remaining in PN means accepting a diminished role; leaving would mean confronting the electoral mathematics of operating as an independent force in a fragmenting political landscape.

Gerakan's predicament exemplifies the trapped position of coalition lightweights. The party, once a significant player in Malaysian politics as a component of the Barisan Nasional and later as part of PH, has found itself relegated to the periphery of contemporary political alignments. Its decision to align with PN was partly a calculation that the coalition would deliver electoral viability and a continuing voice in federal structures. However, the party's leadership recognizes that openly choosing between PAS and Bersatu could precipitate a crisis within its own organization or push members toward other alternatives. Many Gerakan figures likely view neutrality as a survival strategy, allowing the party to negotiate with whichever faction emerges stronger from the current turmoil.

MIPP, as a newer and smaller entity formed by dissidents from PAS itself, occupies an even more delicate position. The party's existence depends partly on its ability to carve out a distinct political space, yet remaining within PN while the party that spawned it battles for dominance creates inherent tensions. MIPP's leadership must consider whether continued PN membership serves its interests or whether the unfolding crisis presents an opportunity to reposition itself—or conversely, threatens its institutional viability if the coalition ruptures entirely.

The electoral realities weighing on both Gerakan and MIPP are substantial and complex. In parliamentary and state elections, coalition endorsement and campaign resources matter significantly. A party that aligns with the losing faction in an internal coalition struggle could find itself marginalized during candidate selection, frozen out of campaign machinery, or even deselected in winnable seats. Conversely, backing the wrong side prematurely could alienate potential allies or invite retribution from the stronger faction. This explains why both parties have adopted a wait-and-see posture, publicly expressing commitment to PN's unity while privately assessing which way the political winds are blowing.

The broader implications of their indecision extend beyond the immediate coalition dynamics. Malaysian politics operates through factionalism and coalition-building, meaning that the behavior of smaller parties during moments of coalition stress sends signals throughout the political system. If Gerakan and MIPP eventually move toward PAS, that signals PAS's consolidation of PN control and potentially Bersatu's marginalization or exit from the coalition. If they attempt to mediate or cushion a split, they might position themselves as kingmakers in subsequent configurations. If they remain neutral until forced to choose, they risk appearing opportunistic or unreliable to whichever faction ultimately dominates.

The tension within PN also reflects deeper questions about coalition politics in Malaysia. The country's complex electoral system, which operates through both federal parliamentary seats and state governments, creates incentives for parties to form broad coalitions but also generates friction when power-sharing arrangements prove unequal or unstable. Small parties like Gerakan and MIPP are particularly vulnerable to these dynamics, lacking the organizational heft of PAS or the political capital that Bersatu once wielded. Their ability to influence outcomes is proportional to their perceived strategic value—which, in turn, depends on maintaining plausible ambiguity about their intentions.

Looking forward, the next concrete test of these parties' commitments will likely come during candidate nominations for upcoming elections or through parliamentary votes on confidence in key positions. These moments will force Gerakan and MIPP to reveal their hands, either by supporting one faction's candidates or by attempting to broker compromises. Until then, their public silence masks intense behind-the-scenes negotiations, internal party discussions, and careful monitoring of which direction the broader political establishment appears to be moving. Their ultimate choice could either stabilize PN by bringing smaller parties solidly behind one faction, or accelerate the coalition's fragmentation if they abandon it altogether.
