"Challenging the liberal nation-state? Postnationalism, multiculturalism, and the collective claims making of migrants and ethnic minorities in Britain and Germany."

According to this perspective, migrants and ethnic minorities contribute through their claims making both to the external erosion of sovereignty (the postnational challenge), and to the internal cultural differentiation of liberal nation‐states (the multicultural challenge).
