Maya Goodfellow joins me to discuss her new book, Hostile Environment: How Immigrants Became Scapegoats. We talked about the historical roots of the hostile environment policy, the punitive, cruel and deliberately confusing character of Britain's immigration system, how viewing migrants as 'economic assets' feeds into anti-migrant politics, and we also chatted about how New Labour's policies on migration and asylum laid some of the basis for the Conservative's migration policies.
