Abstract. This paper is an exploration of national identities among sports people in a community in the Scottish Borders. This group experiences a split in their identities. Publicly, they are ascribed an ambiguous national identity by the surrounding national communities. Privately, and among fellow community members, they unambiguously assert national identity. This paper examines the way this split is managed, arguing that the performance of public ambiguity is expected, but is supported by the private performance of nationality. National identity is analysed specifically as a performance, and sport is the context in which this performance takes place.
