Originally formed in 1980, the All-Party Parliamentary Group on Penal Affairs aims to increase its members' knowledge of penal affairs and to work through parliamentary channels for reform of the penal system.

At an Extraordinary General Meeting on 14 July 2020, Paul Maynard MP was elected a co-chair of the Group. The Group’s other officers are: Lord Ramsbotham (co-chair); Lord Beecham (vice chair); Marie Rimmer MP (vice chair) Andrew Selous MP (vice chair); Lord Hodgson of Astley Abbotts (secretary). The group is listed in the Register of All-Party Groups. An income and expenditure statement for the Group's reporting year is available by clicking here.

The Prison Reform Trust’s head of policy and communications, Mark Day, is clerk to the group.

The Barrow Cadbury Trust kindly supports the Prison Reform Trust to provide the Secretariat to the group.

The group meets regularly and hears presentations from a wide range of people and organisations. Full minutes of meetings are published on the Prison Reform Trust website.
