MP Demands Answers Over Mass Fish Die-Off With No Prosecution in Sight

MP Pushes for Accountability Following Mass Fish Deaths in Cambridgeshire

A Member of Parliament has taken his concerns directly to the floor of the House of Commons, demanding answers over why no legal action has been taken following a devastating fish kill in his constituency.

What Happened at Kings Delph?

In September 2024, approximately 900 fish were found dead in Kings Delph, a dyke located near Whittlesey in Cambridgeshire. Investigations revealed that dangerously elevated ammonia levels, combined with critically low oxygen concentrations in the water, were responsible for the mass deaths. The incident was officially classified as a "category one" environmental incident — the most severe designation, indicating a major impact on water quality, human health, conservation, or local businesses.

At the time, the Environment Agency determined that a pumping station operated by Anglian Water had discharged into the waterway for a continuous 23-hour period following a pump failure. Residents living near the dyke reported feeling deeply distressed, describing the foul smell, discoloured water, and sheer volume of dead fish as both sickening and infuriating.

Barclay Challenges Government in Parliament

Steve Barclay, the Conservative MP for the area and former Environment Secretary, raised the matter directly in Parliament, questioning why no prosecution has been pursued despite the severity of the incident. He called on the Secretary of State to explain the prolonged absence of any enforcement action.

In response, Water Minister Emma Hardy acknowledged the concern and stated she would investigate the matter and respond to Barclay formally in writing. While the reply was measured, it stopped short of providing any concrete timeline or explanation for the lack of legal proceedings.

Environment Agency Cites Complex Investigation

When contacted by media, the Environment Agency confirmed that its investigation — described as lengthy and multifaceted — was formally concluded in December. A compiled file of evidence is now awaiting review by the agency's legal team before any enforcement decision can be made.

In an official statement, an Environment Agency spokesperson said:

"This has been a complex investigation with many different forms of inquiry. We completed the investigation in December and a file of evidence is due to be submitted to our legal team, who will then review it. We cannot provide any further updates until our legal team has reviewed the file and an enforcement decision has been made."

Anglian Water, the utility company responsible for maintaining the dyke and its associated infrastructure, had not issued a public response at the time of reporting.

Community Frustration Continues to Grow

For local residents, the lack of visible accountability has compounded the distress caused by the original incident. Many living alongside Kings Delph expressed outrage at both the environmental damage and the seemingly slow pace of justice. The combination of a foul-smelling waterway, visibly dead wildlife, and months of silence from authorities has left the community feeling overlooked.

With a legal review now underway, the outcome of the Environment Agency's enforcement decision will be closely watched — both by Barclay, who shows no signs of dropping the issue, and by a local community demanding that those responsible are held to account.
