Gypsies, Travellers and Roma are amongst the most marginalised and vulnerable groups in society presenting something of a bellwether, an indicator of the fairness of society. This article charts the development of One Nation Conservatism in the post-war period and relations between the Conservative Party and Gypsies, Travellers and Roma communities to gain insights into the philosophical and moral influences on the current party of government in the UK. It draws on a recent report monitoring UK progress in achieving equality and inclusion for Gypsies, Travellers and Roma groups and concludes that the potential dilution of social justice and human rights agendas will accentuate exclusion.
