determinate

Scotland's prisons currently house 2,037 prisoners serving determinate sentences of four to 10 years, and 465 on sentences of 10 years or more.

We are every single day in this country releasing people through determinate sentencing.

From Tuesday, prisoners on “standard determinate sentences” will be automatically released after they have served 40% of their sentence.

Ms Simpson's best friend Hetti Barkworth-Nanton, who also chairs domestic abuse charity Refuge, said: "This is a landmark decision which has the potential to open up this new power to other dangerous offenders on determinate sentences who chose not to engage in rehabilitation, which is all too common in cases of serious and fatal domestic abuse."

Jones was given an extended determinate sentence, where an offender receives a fixed jail term and an extended period on licence after their release.
