According to Britannica , party systems are broadly categorised as two-party, multiparty, or single-party, depending not only on the number of parties but also on how effectively they compete for control and share power.

In a two-party system, such as in the United States, two main political parties dominate elections and governance, often marginalising smaller players.

In contrast, multi-party systems, like those in much of Europe, allow for several influential parties to form coalition governments, creating a more flexible yet sometimes unstable political environment.

Meanwhile, dominant-party systems, seen in places such as Singapore and South Africa , feature competitive elections where one party nonetheless maintains long-term control, often blurring the line between democracy and monopoly.

A 2025 Pew Research Centre survey across 24 countries revealed that in 15 of them, no political party received a positive rating from a majority of citizens, a stark indicator of widespread political fatigue and disillusionment with established systems.

Analysts suggest that 2025 may mark a new wave of political disruption as voter frustration, digital activism, and populist movements challenge long-standing institutions.

These shifts are already visible in real-world events. In Portugal, the rise of the right-wing populist party Chega broke the country’s half-century pattern of two-party politics, a dramatic realignment that many view as symbolic of a broader European trend.

Across the world, Singapore continues to embody the stability and control of a dominant-party system as the People’s Action Party (PAP) has extended its unbroken rule since 1959.
