An IPP prisoner is someone in England or Wales serving an Imprisonment for Public Protection (IPP) sentence – an indeterminate sentence with no fixed end date, originally used for people a court judged to be “dangerous” but whose crime did not quite meet the threshold for a full life sentence.

What “IPP prisoner” means

  • IPP = Imprisonment for Public Protection. It was introduced in 2005 for offenders considered a serious ongoing risk, even if their offence did not merit a life sentence.
  • An IPP sentence has two parts :
    • A minimum term (tariff) that must be served as punishment for the crime.
* An **indefinite period after the tariff** , where continued detention depends on risk, not on time.
  • An IPP prisoner can only be released when the Parole Board is satisfied they no longer pose a high risk to the public.

In other words, an IPP prisoner has no guaranteed release date and may remain in prison long after their minimum term has expired if they are still assessed as risky.

How the sentence works in practice

  • After serving the tariff , the prisoner can be considered for parole, but release is not automatic.
  • The sentence is indeterminate , so the person can, in theory, be held for life if risk is never judged manageable.
  • Even after release, they remain on licence and can be recalled to prison if they breach conditions or are seen as risky again.

Many IPP prisoners have served years or even decades beyond their original minimum term , which is a core reason the sentence has been so heavily criticised.

Abolition and why it’s still an issue

  • IPP sentences were abolished in 2012 , so courts no longer hand them out.
  • However, the abolition was not retrospective , so people already sentenced to IPP still serve them.
  • As of late 2025, there were still around 2,400–2,800 people on IPP sentences, with hundreds never released at all, and many serving far beyond their tariffs.

Human rights groups, legal charities and parliamentary committees have called IPP sentences “irredeemably flawed”, “toxic” and even “cruel or degrading”, and urged resentencing or some form of systematic review.

Recent news and debate

  • A 2026 submission to the UN’s special rapporteur on torture argued that IPP prisoners face “cruel, inhuman and degrading treatment” because of indefinite detention and severe mental health impacts.
  • Reports describe people serving on average over 500% of their minimum term , with some extreme cases like Thomas White, who served nearly 14 years for robbing a phone and suffered serious mental health deterioration.
  • In January 2026 , five IPP cases were referred to the Court of Appeal, reflecting a slow shift in how the justice system views these legacy sentences, especially for people sentenced very young.

Campaigners continue to push for resentencing , automatic reviews, or other reforms to end or limit these indefinite punishments, while government statements emphasise the need to protect the public from serious harm.

Mini FAQ: quick answers

  1. Is an IPP prisoner the same as a life prisoner?
    • Not exactly, but it is similar : both are indeterminate, but IPP was designed for “dangerous” offenders below the normal life‑sentence level.
  1. Can an IPP prisoner ever get out?
    • Yes, but only if the Parole Board decides their risk can be safely managed in the community; there is no automatic release date.
  1. Why is it controversial?
    • Because many people are held far beyond their tariff , with serious mental health consequences, and because indefinite detention for lower‑level original offences feels disproportionate to many observers.
