On Start the Week Andrew Marr explores the question of citizenship. While immigration issues dominate political debate, little attention is paid to the big increase in the number of people becoming British. The academic Thom Brooks and the Eurosceptic MEP Daniel Hannan look at the relationship between the two and the challenges for modern UK citizenship. Ben Rawlence spent four years reporting the stories of those who are stateless, living in the largest refugee camp in the world, while Frances Stonor Saunders explores the increasing complexity of today's border regimes and the obsession with the verified self.
