What defines a marginal seat in elections?

1. A seat with a large majority

2. A constituency with a small majority

3. A seat currently held by an independent candidate

4. A seat that has never changed party in elections

The correct answer is: A constituency with a small majority

A marginal seat is characterized by having a small majority, making it a highly contested area during elections. This definition is vital because marginal seats often determine the outcome of elections, especially in a First-Past-the-Post electoral system like that used in the UK. In constituencies where the majority is small, usually ranging from a few hundred to a couple of thousand votes, the competition between political parties becomes intense, and campaigns can be particularly strategic and aggressive. This small margin signifies that the seat could easily change hands between parties in subsequent elections, reflecting the dynamic nature of political affiliations among voters. The other options describe different types of seats that do not fit the definition of a marginal seat, such as those with a large majority, independent representation, or consistency in party allegiance over time. These other characteristics imply stability or dominance rather than the competitive nature that defines a marginal seat.
