THOUSANDS of people flooded the streets of London yesterday to demand that the government stick to its promise to clean up Britain’s waters.

More than 130 organisations united to organise the rally after years of untreated sewage, agricultural run-off and corporate negligence has pushed the nation’s rivers, seas and lakes to ecological breaking point.

GMB union, the Wildlife Trust, and Surfers Against Sewage were among those that joined the protest organised by River Action.
