I don't know if things have changed in the UK.
I left the org, and was pressured out of the family home, in 1973. I was 16. Although I got away lightly with physical punishments, I heard plenty of whackings from the back room and toilet areas. It sometimes seemed like a competition to see who could make their kids scream the loudest.
My younger sister fell foul of my father's smackings a few times. I don't know if it got worse as she was only 9 when I was shown the exit door. I can still picture a day (at home) when my father was whacking her for some misdemeanour. Naturally, she started crying. He then continued to hit her because she was crying. Logic check: Hit a kid. Kid cries. Hit kid for crying.
