The Fragmented Mandate
A country with 200 legislative seats uses a closed-list proportional system with a 5% national threshold. In the latest election, five parties cleared the threshold: Party A 34%, Party B 22%, Party C 18%, Party D 11%, and Party E 7%. Turnout was 71%. The president, elected separately by a run-off two weeks earlier, belongs to Party C. Party C ran on a platform of expanding social spending, while Parties A and B campaigned on fiscal consolidation. Post-election talks stall. Party A's leader publicly rules out any coalition with Party C, and Party E says it will support only a government that includes Party C. The constitution requires the prime minister to command a majority in the legislature within 30 days or the president may dissolve the chamber.
1. Using the seat shares and the stated red lines, identify the most plausible governing formula and explain why the arithmetically 'simplest' majority is politically unavailable.

Approximate seat shares (ignoring threshold effects): A ~68, B ~44, C ~36, D ~22, E ~14.
- A+B+D = 68+44+22 = 134 → a majority (101 needed). This is the arithmetically simplest majority and it is ideologically coherent (all favor consolidation). But it excludes Party C, whose leader is the president - and Party E has declared it will back only a government including C. So A+B+D is politically costly: it sets the legislature against the head of state and leaves out the party that can veto via E.
- A+B+C+D = 170 → supermajority but violates A's red line on C.
- C+D+E = 36+22+14 = 72 → short of majority.
- B+C+D+E = 116 → majority, includes C (satisfying E), avoids A's red line. This is the plausible formula: a grand-ish coalition anchored on B and C with D and E.
Why the simplest is unavailable: coalition formation is constrained by ideological distance and veto players, not just seat arithmetic. A's refusal to govern with the president's party plus E's conditionality eliminates the minimal-winning A+B+D. The 30-day dissolution clock raises the cost of deadlock, pushing actors toward the B+C+D+E compromise even though it spans the fiscal-consolidation/expansion divide - a sign that office-seeking and dissolution risk can override policy proximity.
2. Explain how the separately elected presidency changes coalition bargaining compared with a pure parliamentary system, and predict one consequence for policy output.
Read the worked answer
In a pure parliamentary system, the executive emerges from the legislative majority, so the coalition that commands seats is the government and there is no rival center of legitimacy. Here, the president is elected independently by run-off and belongs to Party C (only ~18% of votes, ~36 seats). This creates dual legitimacy: the head of state claims a national mandate while his party is a junior legislative partner.
Consequences for bargaining:
- Party C has outside leverage disproportionate to its seats: it can threaten to obstruct, and E amplifies that leverage.
- Coalition partners must anticipate cohabitation dynamics - the president can use dissolution powers, veto, or public appeals.
- Bargaining shifts from pure policy compromise toward regime-level power-sharing (who controls which ministries, how dissolution risk is managed).
Predicted policy consequence: fiscal consolidation is likely diluted or delayed, because the only majority that includes the president's party (B+C+D+E) also includes the pro-spending C and E. Expect a compromise budget with smaller cuts than A and B campaigned for, and possibly a divided executive in which the PM (from B) and president (from C) publicly disagree - a classic cohabitation pattern.
