So, here we have a Home Office who are failing in the management of an existing task:

Trial judge recommends the offender should be deported on sentence completion. Home Office makes a formal decision to follow that recommendation, then fails to carry it out.

(Note that the judge recommends that the offender be deported, not be considered for deportation. HMG's description is spin.)

Rectifying this requires the Home Office to simply be better at keeping records and communicating between its various Directorates (ie Prison Service tells Immigration that someone's coming to the end of their sentence. Immigration turns up on release day with a plane ticket and a taxi to LHR).

Not rocket science, is it?

But in a desperate attempt to get ahead of the headlines, Ol' Jug-ears decides that what is needed is not better implementation of existing legislation (which is more than adequate - Home Secretaries already enjoy the broadest of discretions to deport people who are non-conducive to the public good), but new, more draconian legislation.

Again.
