'Mega' 1,000-cattle dairy inquiry begins in Powys
A public inquiry has begun into Powys council's decision to refuse planning for a major expansion to a dairy farm housing 1,000 cattle next to a village primary school.
Farmer Fraser Jones wants to build one of the first "mega dairies" in Wales at his farm in Leighton, near Welshpool.
Residents and animal welfare groups have opposed his plan.
