Politics today is commonly associated with 'party politics' where each party represents a certain group of people in Parliament and views issues from a specific angle. Britain has three main political parties: Firstly, the right-wing Conservative Party, which advocates encouraging private property, preserving a strong military and retaining traditional cultural values. Second, the left-wing Labor Party, closely affiliated with the unions, promotes nationalization, a welfare state, and a Keynesian approach to the economy; and the third, the Liberal Democrats in the center who emphasize individual freedom, equality, a mixed economy, a developed welfare state and a reformed democratized system of government. Their main roles are in both the long term and the short term. The long-term goals of a political party include public engagement where parties generate public interest and encourage sustained participation in debates. The short-term role of a political party would be to mobilize the population, by focusing on how people vote in a particular case, during a referendum or an election for example. However, if we take a closer look at the effectiveness of political parties in terms of their role in society, we can notice a gap between what they aim for and the observable outcome. This suggests that there have been changes in the way political parties operate, which could lead to their decline.

Second, the evolution of society and social groups has further harmed political parties, which have had to adapt to a change in voting public. Finally, the loss of power of the British government and its political parties had a negative effect on the population who began to doubt the effectiveness of the parties and contributed to the decline of participation and, consequently, of the parties. All these factors show that British political parties are indeed in decline, but this does not mean that British parties will disappear; As the Hughton Report noted in 1976, “if parties fail, then democracy fails.” Our democratic system needs political parties to function properly; it's not too late for the resurgence of the British party.
