Exclusive: ‘No scientific justification’ to say former nurse definitely poisoned babies with insulin, according to study authors

The claim that Lucy Letby definitely poisoned babies with insulin has “no scientific justification whatsoever” and there is a “very strong level of reasonable doubt” about the convictions, according to the authors of a 100-page study on the case.

Prof Geoff Chase, one of the world’s foremost experts on the effect of insulin on pre-term babies, told the Guardian it was “very unlikely” anyone had administered potentially lethal doses to two of the infants.
