Indeterminate Imprisonment for Public Protection (IPP) is one of the most controversial sentences in the history of British sentencing, creating a ‘general and systemic legal failure’ (Laws LJ in Wells (2007)). Female IPP prisoners represent an often forgotten and overlooked minority, stuck in the creaking penal system. This research provides the first empirical exploration of female prisoners on IPP still in prison, despite the abolition of the sentence in 2012.
