The urban disturbances in Bradford, Oldham, and Burnley in 2001 have brought a renewed interest in the causes, meaning, and consequences of minority ethnic residential segregation in Britain. Official reports into the disturbances highlighted the racialisation of social and spatial relations in these northern cities, where, it has been claimed, white and minority ethnic communities are living``a series of parallel lives'', which can lead to misunderstandings and tensions between them (Community Cohesion Review Team, 2001, page 9). Central to this assertion is the claim that people of South Asian origin, particularly British Muslims, are failing to be active citizens by withdrawing from social and spatial interactions with wider British society. Arguments rest on the apparent ethnic/religious divisions in patterns of settlement and schooling, and deep cultural differences. This isolationist discourse, commonly voiced by politicians and the media, was captured in a report into race relations in Bradford, which referred tò`t he very worrying drift towards self-segregation'' by people of South Asian origin in this city (Bradford Race Review Team, 2001, foreword). More controversially, Peter Hain, then Minister for Europe, also clearly articulated this self-segregation perspective in his comments about Muslims' tendency towards isolationism in Britain (Russell, 2002). The view that many people of South Asian origin are failing to act as responsible citizens has also found expression in popular and political discourses surrounding the use of mother-tongue languages. This was given official sanction by the then Home Secretary David Blunkett's call for British Asians to speak English not only in the public sphere, but in the private sphere of the home (Pallister, 2002). Such concerns are symptomatic of wider (long-standing) anxieties about immigration, citizenship, and national identity in Britain. They coalesce with the moral panic surrounding asylum seekers and refugees, in which grounds for excluding`Others' based on proposals for citizenship tests, oaths of allegiance, and health tests have gained wide popular support.
