Thousands of people have taken to rivers and waterways to protest against water companies dumping sewage in them.
The day of action, organised by the charity Surfers Against Sewage, involves 12 protests across the UK, BBC reports.
In Manningtree, Essex, wild swimmers marched and dressed up in mermaid and giant poo costumes by the River Stour.
Anglian Water, which admitted it dumped sewage in the river 389 times last year, said it was investing millions of pounds to rectify the "historic issue".
Water companies discharged raw sewage into British rivers 372,533 times last year, for a total of more than 2.6m hours, according to data from the Environment Agency.
An Anglian Water spokesperson said: "Data from our 2021 monitoring programme tells us our performance continues to improve, and the increasing visibility we have of combined sewer overflow (CSO) activity gives us even more opportunities to act faster in the areas where we can have most environmental benefit.
