Proportional representation is the system of voting used for European Parliament elections in all Member States. (See EU citizenship: Political rights)

the idea of acting on behalf of someone else. For example, MSPs represent their constituents (the people living in the area where they were elected from). They do this in many different ways, such as holding surgeries in their constituencies where people can raise problems with them, they can ask questions in Parliament, and might even propose new laws to change things. They are expected to represent everyone in their constituency, whether or not the constituent voted for them at the election.

In politics, representation describes how residents of a country are empowered in the government. Representation usually refers to representative democracies, where elected representatives speak for their constituents in the legislature. Generally, only citizens are granted representation in the government in the form of voting rights, however some democracies have extended this right further.
