LONDON (Reuters) -Nurse Lucy Letby will spend the rest of her life behind bars for killing seven newborn babies after a judge on Monday ruled Britain's most prolific serial child killer of modern times should never be released.

Letby, 33, murdered the five baby boys and two baby girls at the neonatal unit of Countess of Chester hospital in northern England over 13 months from 2015, injecting the infants with insulin or air, or force fed them milk.
