Call the Midwife stars were sickened by scenes they filmed showing the effects of Enoch Powell’s infamous Rivers of Blood speech.
The Conservative MP’s speech to fellow Tories in Birmingham in 1968 stirred up racial hatred after he attacked the country’s immigration policy and called for a programme of voluntary repatriation.
Linda Bassett, 72, who plays nurse Phyllis Crane, said: “Our scenes brought it back. I knew he got a lot of support but I didn’t know the dockers came out and marched in support of him [after Powell was sacked]. It made me feel sick but, of course, it’s what happened.”
