Sheen Testifies

Actor Michael Sheen testified before the UK Parliament's Welsh Affairs Committee on 10 September 2026 about his BBC documentary on toxic waste in Wales.
His blood contained 82 different PCBs, including the most carcinogenic compound, stressing the human cost of governmental inaction.
Sheen appeared before the committee alongside investigative journalists Lucy Taylor and Dan Ashby.
Whistleblower Douglas Gowan claimed tonnes of PCBs were dumped across Wales and north-west England.

Blindspot

About 1,000 residents in Wrexham formed the Monsanto Community Action Group to demand clean-up of suspected dump sites highlighted in the documentary.

History

Historical Context

After the 1976 Seveso disaster released massive dioxin, the European Community adopted the 1982 Seveso Directive, tightening safety at sites storing hazardous substances. Michael Sheen’s 2026 testimony before the UK Parliament’s Welsh Affairs Committee, alongside journalist Lucy Taylor and whistle-blower Douglas Gowan, cites that precedent to push a nationwide PCB testing programme for communities such as Wrexham’s Monsanto Action Group.
