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.”
Kate Adie CBE DL
“Unlock recognises that helping ex-prisoners lead normal and fulfilling lives, is beneficial for all. I’m particularly impressed by its practical and supportive approach.”
Professor Andrew Coyle CMG
“Congratulations on the excellent work which you and your colleagues in Unlock continue to do. I have been a firm supporter since the early days when, what was then the National Association of Ex-offenders, was set up.
It is essential that men and women who have been in prison and who have paid their debt to society should be helped to resettle into civil society. Who better to give them help to do so than those who have already trod that path. Unlock has provided support of this kind over the last 15 years and I value my role as a Patron.”
Flo Krause LLB
“I wholly support Unlock’s aims and values. The work that Unlock has done so far in pushing for social rehabilitation of people coming out of prison is invaluable.
I am thinking specifically about the bank accounts and insurance. I am also thinking about the work on the recent Rehabilitation of Offenders Act. I am proud to be associated with Unlock and all that it stands for and I hope that it continues to grow from strength to strength and continues to make the impact that is so needed on our society in terms of embracing rehabilitation.”
Dr Silvia Casale CMG
“I am constantly impressed by the practical help a small but energetic organisation like Unlock has been able to provide to people in a wide variety of circumstances. Over the years it has been ...
inspiring to meet many individuals who have turned their lives around and are making such a positive contribution to their communities with the help of Unlock.”
Dr Deborah Cheney
“What can I say? There is SO much to comment upon about those in prison and those who have been in prison and are trying to recover their lives. Prison, by the very nature of how it operates, both undermines and ‘reduces’ people.
Whatever the legislation states, whatever the Prison Rules decree, there is no doubt that the very nature of being imprisoned both diminishes the prisoner as a person and the families of those imprisoned. The fact that Unlock exists is a shame, it exists because when someone has served a sentence their lives may be blighted forever, any future they may envisage is corrupted. The very fact Unlock exists is a blessing, there is at least an organisation which may champion those who have been in prison and face such a future. Unlock believes that fate is not inevitable, nor is that societal labelling. Unlock challenges ordinary perceptions with examples. Who else would do it?”
Dr Shadd Maruna
“It is an honour to be associated with Unlock — you are doing great work”
Jill Stevens
“The real strength of Unlock is that it is not only run by people who understand the huge challenges faced by those with past convictions, but also that as an organisation it knows how to effectively bring those challenges to the attention of decision makers who can help.
I have been impressed by the impeccable and compelling research done by Unlock, particularly in my area of expertise, personal finance. This research and resulting reports has provided robust and professional back-up to their various campaigns. Much of Unlock’s success undoubtedly stems from the strategy of working with government and private organisations to educate those influencers who have the power to change things for the better. I have seen the difference the organisation makes, both on a small scale to individuals and in the larger arena of communities and national understanding, and I am proud to be a patron of Unlock.”
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.”
Baroness Helena Kennedy KC
“I am so proud to be associated with Unlock. It is a terrific organisation. It does such important work supporting prisoners rebuild their lives on release from prison.
It is often one of the the hardest parts of doing time – stepping back into a world fraught with challenges and negative judgements. I have seen first hand how my former clients needed help and Unlock was the answer.”
Dexter Dias KC
Dexter Dias KC is a human rights barrister (King’s Counsel) who played a pivotal role in public inquiries including the Zahid Mubarek Inquiry.
He won the TMG award for Outstanding Contribution to Advocacy and Justice and was finalist in Liberty and JUSTICE’s prestigious Human Rights Lawyer of the Year Award, nominated for “his outstanding commitment to the rule of law and justice for all; for his deep devotion to ensure that the voices of the weakest in society are heard.”
