Thousands join protest to demand clean-up of UK’s filthy waterways

Thousands of people have formed a human river and marched through central London, demanding cleaner water.

Environmental activist and TV presenter Chris Packham led rowers and campaign groups asking for government action to clean-up the UK’s rivers and seas.

Protesters promised to turn out and do it all again if nothing happens in the next few months. Keme Nzerem reports.
