Dr Evans’ evidence was challenged strongly during the criminal trial, as Letby’s legal team first tried to block his opinion being put before the jury and then they probed him on his clinical experience and ability to offer expert comment, particularly on air embolus.
He has assembled an international panel of experts to analyse the evidence in the Letby case and come to independent conclusions on the causes of deaths of the babies.
Tuesday’s press conference was called by Letby’s legal team led by barrister Mark McDonald, it was opened by Sir David Davis, but it was Dr Shoo Lee who did most of the talking.
All of this evidence was placed before the jury during the course of Letby’s trial, as part of the prosecution’s case that she was responsible for the deaths.
A substantial amount of focus had remained since Letby’s convictions on Dr Evans, as he has faced accusations that his opinion on some of the baby deaths has "changed".
