Our patrons

Bob Turney
“As one of the founders of Unlock, I was delighted when I was asked to be a Patron of the Charity. It is doing splendid work in helping people to move beyond their pasts and create different lives.”
Professor Nick Hardwick
“I am really pleased to have this opportunity to support Unlock whose work I have admired for a long time.
We all sometimes need a chance to make a new start – and this is particularly true of former prisoners. It is in no-one’s interest to put unnecessary obstacles in their way of building a new productive and law-abiding life – it harms not just former prisoners themselves but their families and the communities of which they are part. Unlock has won praise for the work they have done to help prisoners make the transition through the prison gates and I am pleased to be able to support them.”
Dr Shadd Maruna
“It is an honour to be associated with Unlock — you are doing great work”
Matt Hyde FRSA
“People with convictions face so many obstacles to rebuild their lives – whether that be discrimination or lack of practical support. This does them a disservice and is damaging for wider ...
society. Unlock is a brilliant charity because it works to remove these barriers creating a fairer and more inclusive society and I’m proud to be one of its Patrons.”
The Rt Hon. the Lord Garnier KC
“Prisons are a secret world known only to those who work or are imprisoned within them. To the public on the outside it is far too often a matter of ‘out of sight, out of mind’. Unlock is one of the vital metaphorical windows through which the public can see into the closed world of the prisoner and learn what is being done in their name,
and through which the prisoner can see out into society and know that there is a place of hope and acceptance for him or her once they have completed their sentence. Unlock does invaluable work and without it Britain would be a poorer place.”
