Step-by-step explanation:
In a parliamentary system, a minimum winning coalition refers to the smallest group of parties that can form a majority in the legislature. In a multi-party situation where no single party has a clear majority, parties often need to join together in coalitions to create a majority in the chamber.
For example, in the 2020 Irish elections, no single party gained a majority. The party that gained the most votes, Fianna Fáil, joined with two supporting parties, Fine Gael and the Green Party, to form a majority coalition.
A minimum winning coalition is important to ensure that the government can pass legislation and effectively govern.
