@Newsenmum we have no idea why he was in touch with a paedophile.
One possibility - he was actively seeking out paedophiles to chat to. Seems unlikely given he asked the one he was in touch with to stop sending the illegal images
Another possibility - he's a closest gay man who is attracted to men who are younger than him. He meets people on line to share legal porn images one of whom starts by sending legal images but keeps trying to send illegal ones. Huw is an idiot who doesn't block or report him.
Am sure there are multiple other possibilities. We don't know, maybe sentencing remarks will tell us more.
