Conservationists in Denbighshire are expressing anger and heartbreak over the potential death of more than 1,000 toads after a Welsh water company drained the Nant-y-Ffrith reservoir during the amphibians' breeding season.

Marine investigators say the death may be linked to a group of grey seals operating between Wales and Devon.

Welsh Water has issued an apology and faces a proposed £44.7 million enforcement package from regulator Ofwat, following findings of serious and unacceptable breaches in its sewage and network operations.

Ofwat said it found “serious and unacceptable” breaches in Welsh Water’s sewage works systems and operations.
