A dual mandate is the practice in which elected officials serve in more than one elected or other public position simultaneously. This practice is sometimes known as double jobbing in Britain and cumul des mandats in France; not to be confused with double dipping in the United States. Thus, if someone who is already mayor of a town or city councillor becomes elected as MP or senator at the national or state legislature and retains both positions, this is a dual mandate.

The European Parliament (EP) is one of the legislative bodies of the European Union and one of its seven institutions. Together with the Council of the European Union, it adopts European legislation, following a proposal by the European Commission. The Parliament is composed of 705 members (MEPs), due to rise to 720 after the June 2024 European elections. It represents the second-largest democratic electorate in the world, with an electorate of 375 million eligible voters in 2009.
