This chapter argues that the ideas of duty and responsibility defended by communitarianism were used by New Labour to water down the party's commitment to equality. It begins with a brief explanation of communitarian ideas, and focuses on the works of 'prescriptive communitarians', given that it was these thinkers who had an influence on New Labour's thinking. The chapter deals with the link between ideas on community and socialism. The idea of community was present in Tony Blair's Third Way pamphlet, in which he defended a 'politics of "us" rather than "me"', one that would be based on 'an ethic of responsibility as well as rights'. The chapter is concerned with the narrative on social exclusion-social inclusion, which sheds light on New Labour's approach to poverty and social inequalities. It ends with a discussion of the implications of those deviations for the party's ideology.
