Statement said: "I am making changes to slow the path to settlement for refugees, and those granted humanitarian protection, who have committed crimes. Applications for settlement from refugees will be refused for 15 years from the date of their sentence if they have been sentenced to over 12 months’ imprisonment; for 7 years if they have been sentenced to up to 12 months’ imprisonment; and for 2 years if they have been given a non-custodial sentence. Discretion to delay the route to settlement will apply in the case of repeat offenders."
Not 'committed' crimes, rather 'been caught and convicted of a crime'.
I guess it is a start, and possible the best they could do. I'd settle for 25 years delay for any conviction myself. Maybe even ensure those with sentences >2 years are removed from the country (but where to if they have claimed asylum - all the ECHR issues then come to bear).
