On 21 April 1968 at Birmingham’s Midland Hotel Enoch Powell addressed a Conservative Association meeting and delivered his incendiary “Rivers of Blood” speech which divided the UK in much the same way that the Brexit vote 50 years later divided the UK.
Chris Hannan’s purpose in What Shadows is not to lambast Powell (a crisp and impressive performance from Ian McDiarmid), who is treated most sympathetically, but to encourage a more open discussion about who as a nation we think we are and where we stand in our views on immigrants.
