The institution of the presidency has played a major role in influencing competition between parties since the foundation of the Fifth Republic in 1958, and this would be particularly true of the 2017 elections. Macron was able to gain support despite not representing an established party, and once elected, the logic of the institutions enabled his party to gain a majority in the National Assembly. His success was also enabled by the breakdown of longstanding links between the electorate and the traditional ideologies that they used to support, and the adoption by many voters of a more volatile and individualist approach to politics. These factors undermined the traditional arrangement of the party system and would be crucial in determining the fortunes of the Centre Right.
