Thames voted 'worst river' in England and Wales

Help

The Thames is the worst river in England and Wales according to a poll, despite major efforts to clean it up in recent years.

The Wye, which starts in mid Wales, winds over England's border and back and runs into the Severn Estuary was voted the public's favourite.

The survey was conducted by the Our Rivers campaign, which aims to celebrate the nations' rivers and highlight threats to wildlife.
