How does proportional representation shape coalition politics in Scandinavian democracies? Illustrate with the Swedish example.

Proportional representation (PR) translates vote share into near-identical seat share, making single-party majorities structurally improbable. In Scandinavia, this has institutionalised coalition and minority government as the norm rather than the exception, with Sweden's 2026 election offering a textbook illustration.

How PR is designed in the region

• Sweden's Riksdag has 349 seats, of which 310 are fixed constituency seats and 39 are adjustment ("levelling") seats that correct national disproportionality [1].
• A 4% national threshold (or 12% within a constituency) filters fringe parties while still admitting six to eight viable parties [2].
• The result: no Swedish party has won an outright majority in the modern era, so 175 seats must be assembled, not won.

How this shapes coalition politics

• Bloc formation replaces party contest: parties pre-commit to centre-left and centre-right blocs, so voters effectively choose a coalition.
• Minority governments are viable because of negative parliamentarism — the Speaker's nominee for PM is confirmed unless 175 MPs vote against, a rule made compulsory by the 2011 Instrument of Government amendment [3].
• Confidence-and-supply arrangements let a party sustain a government without cabinet seats, creating kingmakers disproportionate to their size.
• Fragmented mandates raise governability costs: prolonged bargaining, policy dilution and unstable budgets.

The Swedish illustration

• In 2022, the Sweden Democrats won 73 seats (20.5%) to become the second-largest party, yet stayed outside the cabinet, backing Ulf Kristersson's Moderate-led minority government externally [4].
• The 13 September 2026 election produced a near-tie — preliminary counts placed the centre-left bloc at roughly 175 seats against 174 for the governing bloc [5] — with the far right pressing for formal ministerial office [6].

PR thus converts electoral pluralism into negotiated governance: it maximises representational fairness while shifting the real contest from the ballot to post-poll bargaining. Sweden shows that stability then depends less on numbers than on coalition norms and constitutional devices like negative parliamentarism — a balance worth studying as India debates electoral reform and representational fairness.
