Minority Cabinet

A minority cabinet (also called a minority government) forms when the party or coalition holding executive office controls less than 50% of seats in the legislature's confidence chamber. To survive votes of confidence and pass budgets, it must secure backing from non-cabinet parties on a vote-by-vote basis, through a formal confidence-and-supply agreement, or via legislative toleration by an external party.

Minority cabinets are common in parliamentary systems with proportional representation and fragmented party systems. They are routine in Scandinavia: Sweden and Denmark have governed by minority cabinets for most of the postwar era, often functioning effectively because of strong committee systems and consensual policymaking norms. Canada has also seen frequent federal minority governments, including those led by Lester Pearson (1963–1968), Paul Martin, Stephen Harper (2006–2011), and Justin Trudeau (from 2019).

The arrangement typically takes one of several forms:

• Single-party minority — one party governs alone and negotiates support issue-by-issue.
• Minority coalition — two or more parties form a cabinet that still falls short of a majority.
• Confidence-and-supply — an external party pledges to support the government on confidence motions and budgets in exchange for policy concessions, without taking ministerial posts. The 2017–2019 agreement between the UK Conservatives and Northern Ireland's DUP under Theresa May is a well-known example.

Advantages include flexibility, broader cross-party negotiation, and accommodation of fragmented electorates. Disadvantages include legislative instability, shortened terms, difficulty enacting controversial reforms, and the risk of being brought down by a no-confidence vote. In some systems, constructive vote of no confidence rules (as in Germany's Basic Law, Article 67) make minority cabinets more durable by requiring opponents to agree on a replacement chancellor before ousting the incumbent.
