The Clink Charity trains prisoners to help them gain their City and Guilds National Vocational Qualifications in hospitality and horticulture.
Finlay Scott, chairman of The Clink Charity, said: “Chris has taken the Clink from a single start-up training restaurant to being one of the most effective organisations reducing re-offending in the UK.
“On a personal note, I will miss Chris as both a friend and a colleague. He leaves The Clink in a very strong position having restructured the organisation to continue its brilliant work after he has gone.”
This sector led training programme reduces the risk of a person reoffending by up to 65.6% according to research.
Chris Moore, chief executive of The Clink Charity, commented: "I am immensely proud of what we have all achieved as a team and what our students and graduates continue to achieve daily.
“None of this would have been possible without the generosity of our funders, suppliers, supporters, customers, The Clink team, directors, trustees and HMPPS. I would like to thank them all for their help and support over the years.
“I will be leaving The Clink Charity at the end of this year to take up a new role (yet to be announced) within the industry, where I can continue to work with those in society that sometimes get overlooked.
“The Clink has, and will, continue to demonstrate what can be achieved when society collectively engages to help those who want and deserve a second chance; it has been an honour to be able to play a part in that.”
