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 Annual General Meeting held on 20 April 2021, Paul Maynard MP and Lord Rambotham were elected co-chairs of the Group; Marie Rimmer MP and Andrew Selous MP were elected vice chairs; and Lord Hodgson of Astley Abbotts was elected 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.
