Looking at the history since the late 90s, it feels like every alliance—whether it was the UPA, NDA, or various state-level fronts—runs into trouble within a couple of years. Is it mainly about ideological mismatch, or do personal ambitions and ministerial portfolios play a bigger role? I am particularly curious about how smaller regional parties leverage their position once they are part of a ruling coalition.
The stability of coalition governments in India has been a defining theme in the country's political history, particularly from the late 1980s through the late 1990s and across various state assemblies. While India has also seen successful, full-term coalition governments—such as the Vajpayee-led NDA and the Manmohan Singh-led UPA—the structural design and political dynamics of multi-party alliances in India make them inherently prone to friction and sudden collapses.
Several key factors explain why multi-party governments in India frequently struggle to complete their terms:
In many instances, coalitions in India are formed after elections purely to reach the majority mark of 272 seats in the Lok Sabha (or a simple majority in state legislative assemblies), rather than on shared core ideologies. When regional parties with wildly different socioeconomic agendas form an alliance solely to keep a dominant party out of power, internal policy disputes emerge almost immediately. Without a pre-poll shared agenda, every major policy decision becomes a potential breaking point.
India’s federal system features powerful regional parties focused on state-specific issues, river water sharing, local electoral dynamics, and specialized central funding requests. When a national party relies on smaller regional partners to maintain a majority, these regional players gain disproportional leverage. Threatening to pull support becomes a routine bargaining tactic to extract policy concessions or ministerial berths for state leaders.
Historically, some of India's most fragile national coalitions—such as the Janata Dal governments led by V.P. Singh and H.D. Deve Gowda, or Chandra Shekhar’s brief administration—relied on large parties providing outside support. Parties supporting a government without holding cabinet posts face zero accountability for governance failures. They can withdraw support at the first sign of public dissatisfaction or electoral miscalculation without losing executive power themselves.
Coalition politics often gathers heavyweights who harbour prime ministerial or chief ministerial ambitions. Personal rivalries between coalition leaders frequently overshadow governance goals. Minor slights, disagreements over cabinet portfolio allocations, or perceived disrespect toward regional party bosses can swiftly lead to public spats and pulled support.
National coalition partners are often direct competitors in state assembly elections. A regional party supporting a national party in New Delhi might be fighting against that same national party in its home state. This electoral rivalry makes long-term cooperation nearly impossible, as partners cannot afford to look subordinate or overly cooperative ahead of local polls.
While the anti-defection law (Tenth Schedule of the Constitution) was designed to prevent individual floor-crossing, entire parties pulling out of alliances remains completely legal and remains the primary mechanism through which multi-party administrations fall apart.
