High Quality Content by WIKIPEDIA articles! In England and Wales, life imprisonment is a sentence which lasts until the death of the prisoner, although in most cases the prisoner will be eligible for parole (officially termed "early release") after a fixed period set by the judge. This period is known as the "minimum term" (previously known as the "tariff"). In some exceptionally grave cases however, a judge may order that a life sentence should mean life by making a "whole life order."
