Does a life sentence always mean that someone will spend the rest of their life in prison?
Some prisoners will stay in prison for the rest of their lives because of the nature of their crimes, although few prisoners receive a whole life tariff (currently 25 out of a total of 5500 lifers). Most receive a set tariff, and the length of time they spend in prison depends on this and whether, at the end of this time, they pose a risk to the community.
