Senn, formerly head of health statistics at the University of Glasgow, was one of 24 signatories to a private letter sent to the health and justice secretaries in July 2024, seen by the Guardian, calling for the Thirlwall Inquiry into the Countess of Chester deaths to be postponed or have its terms of reference changed. The signatories, mostly doctors, nurses and scientists, said they were not associated with Letby or her defence.
