Who Should We Let in? Ian Hislop on the First Great Immigration Row (BBC 2/HD | 9:00pm 10:00pm | Thursday 22nd June 2017)

Ian Hislop takes an entertaining, provocative look at the decades from the Victorian Era to the First World War, when modern Britain introduced its first peacetime restrictions on immigration. The Victorians had an open door to foreigners, drawing no distinction between economic migrant and asylum seeker. But rising immigration in the late 19th century triggered a debate fuelled by clashing values, economic anxiety and the media. Winston Churchill spoke out against the tough curbs proposed by the 1902 Royal Commission, lambasting it as the work of prejudice and racism. But the 1905 Aliens Act restricted peacetime immigration for the first time. Ian also examines the role of the press in stoking fear and prejudice against migrants, discusses attitudes to immigration then and now with Alan Johnson, Baroness Warsi and Katie Hopkins, and takes the temperature of the nation in animated conversation with native and foreign-born Brits in London, Liverpool and Folkestone.
