Exclusive: Research finds ‘worrying’ surge in support for hard-right narratives on national identity

The number of people who believe “Britishness” is something you are born with has almost doubled in two years, according to research that warns of a rising tide of ethno-nationalism in Britain.

Although a majority of the public still believe being British is rooted in shared values, a growing proportion see it as a product of ethnicity, birthplace and ancestry, according to analysis carried out by the Institute for Public Policy Research (IPPR) and shared with the Guardian.
