Lucy Letby is the UK's most prolific child killer in modern times.

Nurse Lucy Letby "did her utmost" to conceal crimes by varying the ways she harmed babies, the Crown Prosecution Service has said.

The 33-year-old was found guilty of murdering seven babies, attempting to murder another six and the jury was undecided on the attempted murder of a further four babies.

She was found not guilty of two counts of attempted murder.
