“You don’t care. You only pretend to care!” an exhausted, homeless Cathy shouts at a board of welfare officials just days before her children are taken from her. It’s a scene from Cathy Come Home, the 1966 BBC drama that remains – 60 years on – a touchstone for discussions on homelessness. Written by Jeremy Sandford and directed by Ken Loach, the television play follows Cathy and her husband Reg, who are expecting a child when Reg loses his income through injury.
