As part of the government?s mission-driven approach to tackling crime, MoJ, the Cabinet Office, HM Treasury, the Home Office and other government bodies should work together to review the coherence of the government?s policy objectives and the size of, and funding for, its prison estate so they can be clear on spending priorities. This should include policies internal to the justice system such as on remand, parole and sentencing; and wider government objectives in areas such as policing, health and immigration. Specifically:
MoJ should use existing cross-government mechanisms to seek agreement on how to improve alignment between government objectives which impact the prison population, and on the capacity required to support these aims. This should include the level of risk the government is willing to tolerate around capacity pressures in the estate;

This should include policies internal to the justice system such as on remand, parole and sentencing; and wider government objectives in areas such as policing, health and immigration. Specifically:
HM Treasury should assess whether MoJ?s suggested funding approach would provide better value for money than current arrangements, such as in other areas of government where multi-year funding arrangements are in place.
