The sentence of Nottingham knifeman Valdo Calocane has raised questions about what other options could be available if Court of Appeal judges did reconsider the case.

UK Labour leader Keir Starmer added his voice to calls for an inquiry into any failings that led to the attacks after the families of the three people Calocane killed reacted angrily to the sentencing, accusing prosecutors of a “fait accompli” in accepting a guilty plea to manslaughter by diminished responsibility rather than pursuing murder charges.
