Prisoner Releases in Error

Baroness Chakrabarti Excerpts

Thursday 13th November 2025 Lords Chamber

[Baroness Chakrabarti (Lab)]

My Lords, I am grateful to the Minister, but on this occasion also to the noble Lord, Lord Marks of Henley-on-Thames, for the bipartisan nature of his question focusing on this lack of digitisation, which I find completely flabbergasting in the context of such a massive prison estate when we live in such a digital world. This is not just about record-keeping; it is about sentence calculation as well in the context of an incredibly complex statute book. I am sometimes sceptical about artificial intelligence, but on this occasion I think it is an obvious fit for something that is essentially a complex mathematical equation that could be greatly assisted by AI. Can the Minister assure the House that that aspect of his answer will be prioritised, that the contract for the development of this technology will be firmly gripped in the context of procurement and that the sovereign capacity will be beefed up?

--- Later in debate ---

[Lord Carter of Haslemere (CB)]

My Lords, as has been said, prisoners have been released in error for decades. I know because I used to advise on sentence calculation in the 1990s in the Home Office legal advisers branch and I was the Prison Service legal adviser. It was difficult then; it is now fiendishly difficult because of all the changes to the statute book that have happened since then, as the noble Baroness, Lady Chakrabarti, knows well, because she was with me at the Home Office.

[Baroness Chakrabarti (Lab)]

The noble Lord was my boss.

[Lord Carter of Haslemere (CB)]

I was indeed. The statute book is a total mess as far as trying to calculate when a release date applies for a particular prisoner. Prisoners are all in a different position. Some have additional days; some have served a different remand time. All these factors need to be taken into account. As the noble Lord, Lord Marks, and the noble Baroness, Lady Chakrabarti, said, a digital answer has to be the way forward. As the noble Baroness said, it will obviously work here because you can punch in the details of the sentence to work out exactly when the release date is. It will have to be updated, of course, as additional days are added to the sentence and so on. We must go to a digital solution, but how long will it take for that to be up and running? There needs to be a procurement process. These things take ages, and we do not have ages. We have identified a crisis taking place. Is there any estimate of when this will be up and running and functioning to stop these releases?
