Is there any law requiring one to wear clothes in your own paddock? I think not.
As for snooping on your neighbours and voyeurism……
One of our (female) neighbours has been known to sunbathe naked. I was a bit surprised but made a point of averting my eyes…seriously, which is I think what any normal bloke would do.
So I suspect there might be more to this vexatious claim than meets the eye….so to speak.
Coincidentally, the TV presenter Kate Humble was being interviewed on Radio 2 this morning. She lives on a small farm and I recall her once saying how she likes to walk naked around her fields. No Sun scandal there, though. Presumably because she has no vexatious neighbours.
