Main contribution

Lord Sumption, a Justice of the Supreme Court from 2012 to 2018, was reported in late March 2025 as saying he had reviewed the case and concluded there were 'serious anomalies' casting doubt on the safety of Letby's convictions, despite what he called an 'impeccable' summing up by the trial judge and a Court of Appeal that had 'meticulously examined the evidence' before refusing permission to appeal.

Key claim

He was quoted as saying the prosecution's theories of how Letby attacked her victims 'seem very speculative', that the case against her was 'circumstantial', and that those questioning the convictions - 'many lawyers and scientists' - are 'too numerous and too well qualified to be dismissed as troublemakers'. His reported conclusion: 'On the material presently available, I believe Lucy Letby was probably innocent.'
