In the UK, manslaughter is the unlawful killing of another person where the killer lacked the mens rea (intent to kill or cause grievous bodily harm) required for murder, either because of a partial defence (voluntary manslaughter) or because the death resulted from negligence or an unlawful act (involuntary manslaughter). It covers killings where intent to kill is present but reduced by factors like loss of control, diminished responsibility, or a suicide pact, and also unintentional killings from gross negligence or dangerous, unlawful acts.
