Speaking after today's hearing Solicitor General Oliver Heald, who referred the sentence to the Court of Appeal for review, said: "It is hard to overstate the seriousness of this crime."
Carl Mills murdered three generations of the same family, leaving a chasm of grief.
I asked the Court of Appeal to look again at this sentence, as despite it being a life sentence with a term of 30 years minimum, the fact remains that Mills denied having set the fire and maintained that stance at trial.
I am thankful that the Court of Appeal has today increased his minimum term to 35 years and I can only hope this offers some degree of reassurance to the public.
