My Lords, I thank the noble Lord, Lord Farmer, for securing this debate and his excellent opening speech. The noble Lord has campaigned tirelessly on prison reform as he has on family life, so he unsurprisingly stressed, with others, the importance of pr

My Lords, we agree with the Statement that the Government clearly inherited a crisis of prison spaces, and a crisis in our criminal justice system as a whole. Frankly, the crisis was clearly attributable to many years of neglect, principally under the la

My Lords, we on these Benches fully support these designations. We consistently supported the proscription of the IRGC throughout the passage of the Crime and Policing Act, to which the Minister has referred. It had been our party policy for some years,

Imprisonment for Public Protection Prisoners

My Lords, the noble Baroness’s view is undoubtedly that employment tribunals are intended to provide a cheap, efficient and effective way of resolving employment disputes. If she shares that view, does she not therefore agree that the issues raised by th

My Lords, these issues are very difficult, but we share the Government’s determination to ensure that we do not run out of prison cell space as a result of past serious underprovision. However, I have two questions on early release. First, can the Minist
