The New Labour Governments encouraged the emergence of a multi-dimensional language policy, in particular as regards education, the competitiveness of businesses, but also the representation of the Kingdom in the eyes of foreigners. However, none of the vernacular languages of ethnic minorities with a migrant background has benefited from statutory protective measures, unlike Celtic languages, under the dual impetus of the devolution process and the ratification by the United Kingdom of the European Charter for Regional or Minority Languages. The aim is to measure not only the societal and economic challenges of such initiatives, the possibility of their sustainability, even though they may in particular appear to contradict the reforms of the Nationality Law of 2004 and 2005, and whether or not they promote the construction of strong local and civic communities.
