Ahmed’s childhood was very British in every way – except for the fact that he was brown. Half English, half Sudanese, he was raised in 1970s London at a time when being mixed-race meant being told to go home, even when you were born just down the road. The memoir by the Editorial Director of BBC News makes the case for a new conversation about race in Britain through personal stories, political analysis and a passionate belief in the ultimate good of this country. He talks to Thea Lenarduzzi of the TLS.
