Summary of the letter

Consultant paediatricians

We, the undersigned consultants, are no longer able to continue to discharge our professional duties in good conscience without an external investigation by the police.
Exhibit to Thirlwall Inquiry, letter dated September 2016

Consultant paediatricians

We have raised our concerns through the appropriate internal channels on multiple occasions since July 2015. We now believe that the cluster of unexpected deaths on the neonatal unit, and the common factor we have independently identified across those deaths, require an investigation of a kind that this Trust is not competent to undertake on its own.
Exhibit to Thirlwall Inquiry

Consultant paediatricians

We write jointly because any one of us could be dismissed if we wrote alone, and because we do not wish any single clinician to bear the weight of this concern.
