Avtar Brah, while discussing the politics of diaspora, stresses that it represents a historical narrative of journeys concerning establishing residence in another place outside the home country. Faced with such journeys full of unequal relationships between classes and races, it is necessary to consider different forms of relations within diasporic communities and various experiences of exile (Brah 1-9). For individuals within a diasporic community, the recognition of a ＂homing desire＂ is not restricted to ＂returning homeland＂ but also includes being declared citizens in the country they have chosen to settle in, and this can be seen as needs for a sense of belongingness. Following Brah's framework, this article discusses the representation of diaspora in HanifKureishi's The Buddha of Suburbia. This novel offers illuminating perspectives on the diverse cross-boundary phenomena observed by the South Asian community in South London. These phenomena are shown as continuous conflicts between the mobile immigrants and the locals born hybrid who come from suburban South London, and the white locals who resisted their presence in the 1970s. The mobile immigrants and the hybrid born locals' pursuits of being integrated into a cosmopolitan community have not been fully supported by the government authorities. However, such conflicts do not prevent the immigrants and hybrid born locals from expressing their needs to belong, by creating and calling for the recognition of a new way of being British. Hence, the issue of belongingness may offer an important key to the contemporary meaning of diaspora in Britain, which was once the dominant country in an imperial system, but then found itself the new home of many of its former subjects.
