Tragically, it was Lucille, not Cyril, who turned out to be correct, with some 1,000 London dock workers marching out in support of Powell when he’s swiftly sacked from his post as shadow defence secretary. Perhaps worse, though, is the reaction of Greta Pickard (Phoebe Thomas), an overworked pregnant mum with whom Lucille has been getting along with famously until this point.

“He just goes on and on, nurse,” Greta says of her husband Wally (Richard James-Neale), who it soon transpires is a staunch supporter of Powell. “It’s like he’s boring into my brain.”

It seems, for a while, as if Greta is immune to her husband’s racist rhetoric. During her labour, though, she becomes exhausted and overheated, and lashes out at Lucille over the repeated physical examinations. She wants gas and air, and so when Mrs Patel (Hiral Varsani), who is further along in her labour than her, is taken straight through to the delivery room ahead of Greta, she sees red.

“I didn’t realise I was in a queue,” she snaps, showing us how quickly people seek to blame others for their own misfortunes. “You know, Enoch Powell was right; it’s bad enough being shoved in a corner, let alone being left alone in bloody agony because of somebody who has no right to be here coming in and here queue-barging like the place belongs to her.”

Quietly, Lucille replies: “Mrs Patel is having her first baby. She’s better off in a delivery room if there are complications.”
