During most of the twenieth century, British politics was dominated by two political parties and it still is
Political duopoly
politics being dominated by two main political parties
From 1951-64 the Conservative party was in parliment permentantly and again in 1979-92
New Labour was in power from 1997-2010
There is a self-fulfilling belief that a vote for a minority party is a wasted vote
two-party system/ political duopoly
a distribution of political power in which two dominant political parties share power between them
The decline of Westminister duopoly was also facilitated by growing partisan dealigment as voters increasingly voted on specific issues rather than according to class
Two-and-a-half patry system
distribution of political power in which a third smaller party can sometimes hold the balance of power between the two more dominant parties.
