The convictions of former nurse Lucy Letby, serving life sentences for the murder and attempted murder of multiple infants, were challenged as a major injustice by an MP at a news conference where medical experts questioned the prosecution's evidence, with neonatologist Shoo Lee asserting that deaths attributed to Letby resulted from natural causes or poor medical care. The case is to be reviewed by the Criminal Cases Review Commission, while a public inquiry and police investigation into neonatal care at the hospital continue.
