Prisons.
Prison system and rehabilitation
Each row is one party. The bar shows how its MPs voted relative to a neutral midpoint — to the right = on-side with the majority position, to the left = opposed. The percentage figure is the share of that party’s MPs who took the same side: higher = more whip-disciplined, closer to 50% = a freer vote.

| Date | Motion | Aye | No | Carried |

| 29 Oct 2025 | Sentencing Bill Report Stage: New Clause 19 Aye: Support pushing ahead with homicide law reform and mandatory re-sentencing of IPP prisoners now, rather than waiting for further reviews · No: Oppose legislating ahead of the Law Commission's homicide review, and reject the mandatory IPP re-sentencing timetable as proposed | 173 | 321 | No |
| 29 Oct 2025 | Sentencing Bill Report Stage: New Clause 12 Aye: Support mandating the government to re-sentence all remaining IPP prisoners within 18 months, providing a firm legal deadline to end a widely condemned form of indefinite imprisonment · No: Oppose imposing a statutory 18-month deadline for IPP re-sentencing, preferring the government to work at its own pace to address the issue without binding legislative commitments it may not be able to meet | 84 | 312 | No |
| 29 Oct 2025 | Sentencing Bill: Third Reading Aye: Support passing the Sentencing Bill into law, including its provisions on sentencing reform, youth justice measures, and potentially addressing the IPP sentencing backlog · No: Oppose the Sentencing Bill in its current form, potentially arguing it does not go far enough on IPP reform, is too soft on crime, or raises other concerns about the legislation | 320 | 103 | Yes |
| 29 Oct 2025 | Sentencing Bill Report Stage: New Clause 20 Aye: Support creating a child cruelty register to monitor and manage offenders convicted of child abuse or neglect, in the same way sex offenders are tracked · No: Oppose the child cruelty register as proposed, likely on grounds that existing measures are sufficient or that the proposal needs further development before being enshrined in law | 184 | 309 | No |

Mapping each Westminster issue to the equivalent council service bucket (so “Prisons” → the matching service line on council finance, with the ranked-spend table this section wants) is its own taxonomy job. Council service spend lives on the council pages today; cross-cut by issue here in a follow-on pass.
