- Keeping criminals in prison is a burden on the taxpayer
- There are problems with prison overcrowding
- The rehabilitative effects of prison are far from certain
One way to help address these issues is to deport foreign criminals upon sentencing. Deport them and declare them persona non grata in the UK for the duration of the sentence. Upon deportation, pass all details of their crime, (evidence, trial, sentence etc) to the authorities in their country of origin and if they judge the misdemeanours of their citizen to be serious enough to warrant a jail sentence, they can hold them in their prisons.
