Sarri Bater

Sarri has spent nearly 30 years as a scholar-practitioner in Conflict Transformation. Sarri's work in system change, transforming structural and cultural violences, peace building and anti-oppression has taken her to live and work around the world. Sarri's practice goes beyond political and technical engagement to include the neuroscience and somatics of violence, power, oppression and systemic trauma, with nature connection practices and deeper spiritual and philosophical resources as key for moving from paradigms of violence to paradigms of peace and justice. Sarri has a passion for the relationship between personal change and transforming structural and cultural violences, and supports organisations and communities in non-violent leadership, alternative systems building, non-hierarchical organising and ways of distributing power.

Sarri specialises in 'identity and difference' conflict and is increasingly in demand to lead work on Systemic Anti-Racism, Diversity, Equity and Inclusion and Decolonising, in institutions, organisations, communities and movements, including local government bodies, philanthropists, activists, and change leaders. Sarri is committed to learning, embodying and developing re-humanising cultures, practices and systems. Sarri's portfolio includes restorative dialogue projects; mediation and negotiation; election monitoring; University lecturing; Truth and Reconciliation projects; detached youth work; working in Maximum Security Prisons; developing understandings and engagement in Hate Crimes; UN Human Rights Council Sessions; independent advisor to police and Home Office on 'community race relations'; school and community mediation projects; European Forum for Restorative Justice... and more.

Sarri holds a First Class Honours Degree in Peace Studies, an MSc with distinction in Transitional Justice, and an LLM in Human Rights, and certificates in many other social technologies, change processes and practices.

Albert Beale

Albert is a militant pacifist, born-again atheist, Londoner, pedant, and Shostakovich junkie; he opposes nationalism without exception. An active member of the PPU and of War Resisters' International since the 1970s, he has frequently represented both in the media, and has held elected office in both. He became a pacifist at school, on a day when someone was hanged "to show that killing people is wrong". Once a computer programmer, then a physics teacher, peace movement jobs include co-ordinator of the Campaign Against Arms Trade, co-editor of Peace News, and editing an international database of peace organisations. Anti-militarist campaigning has included a focus on Northern Ireland and the Middle East; he also campaigns over public transport, nuclear power, censorship, sexual rights, over-consumption, and local democracy - amongst other things. He has a varied experience of (civil and criminal) legal issues in a political context (with a 100% acquittal record).

Davide Dionisi

Davide has been a PPU member for two years. He joined because he is worried about the pro-war policies and militaristic rhetoric that he sees nowadays in the UK, in the EU and in the West. He completely agrees with the PPU strategy of active pacifism, active peaceful resistance to war, active nonviolence, remembrance of civil as well as military victims of wars, and thinks it should be communicated more widely online and in person. Often pacifism is seen as passivity, while the opposite is true. It takes courage to go against the dominant pro-war narratives in the past and today (his two pence on a pacifist slogan: 'Be brave, be a pacifist'). He is keen to help the PPU to disseminate our message of opposition to war and militarism, e.g. by promoting pacifism education, peaceful protests, petitions and other ways of saying 'no' to the inevitability of wars, rearmament and militarism.

Davide is for freedom of movement ('How can a human being be illegal ?', Elie Wiesel), for freedom of speech ('I disapprove of what you say, but I will defend to the death your right to say it' Evelyn Beatrice Hall), for self-determination to be achieved by peaceful means (parliamentary votes or referendums), against the association of war and heroism ('War is organised murder and nothing else', Harry Patch, WWI veteran, hence where is the heroism in joining something that is 'nothing else' than 'organised murder'?) and for a multipolar world or even better for an apolar world where every country is truly sovereign and free to choose not to have enemies and to have friendly relations and trade with any other countries. Sadly, the world we are living in, especially in the West, is very far from his ideals.

Peter Glasgow (Chair) 

Peter was the Peace Education Officer for the Peace Pledge Union from July 2014 to July 2016 and subsequently joined the PPU Council.  At the Annual General Meeting on 29 February 2020 he took up the role of Chairperson of the PPU. Prior to working with the PPU, Peter worked as the Vice Principal, Curriculum in a large, North London College of Further Education and was particularly interested and involved in innovative curriculum development.  He is also a keen cyclist.

Chris Green

In Summer 1973, Chris went to Northern Ireland as a Fellowship of Reconciliation volunteer to work in a youth club in the Creggan Estate, Derry, during the height of The Troubles. Seeing the British Army operating there re-affirmed his commitment to the peace movement. He was also an active member of British Withdrawal from Northern Ireland Campaign. During the second intifada in Palestine, Chris did two summers working as a member of the peace organisation International Solidarity Movement, accompanying ambulances, assisting with the olive harvest and escorting children to school to break the curfew. 

In 2004 he founded, and led for 15 years, the charity White Ribbon Campaign UK, which has become the largest organisation aimed at involving men to challenge men's violence against women. He is now a volunteer director of Male Allies Challenging Sexism and regularly runs events around this topic. In 2007 he was awarded the title “Ultimate Man of the Year,” from the Magazine Cosmopolitan, as a result of his work on challenging men’s violence, and in 2012 was appointed as a UN Leader of Men by UN General Secretary Ban Ki Moon.

Chris founded two printing and merchandising worker co-operatives in Hackney and in Manchester, and later worked as a co-operative and community business development adviser for local authorities, before teaching for 20 years at Manchester Metropolitan University. For relaxation Chris sings in a community choir, Calder Valley Voices, plays football twice a week, cycles nearly everywhere, and is an active member of Todmorden University of the Third Age, leading discussions subjects including The Growth of Militarism.

In 2023-4 Chris was an active member of the Peace Pledge Union fundraising working party and in 2026 of the Remembrance and White Poppies Strategy Group.

Matthew Harbage

Matt has been a peace activist for over 15 years; taking part in protests, petitioning MPs, attending arms companies AGMs and promoting peace in schools and churches. He is an Anglican priest, currently serving as a vicar in north London. Matt has a passion for peace building, motivated by his Christian faith, and believes in strength through diversity of tactics, people and motivations. He joined the PPU Council in 2023 and hopes to support the PPU in building resilience against future wars through peace education and engagement in the public square.

Colin Kerr

Colin joined PPU in the 1980's and has also supported PRET by way of regular donations for some years. Recently retired, he can devote myself to what is important in life - PPU goes into this category! For some months, Colin has been volunteering in the PPU office. Witnessing for peace - pacifist not passive; this is my position. He adopted pacifism as a six former, demonstrated against the Vietnam War (first demo), and many under his belt since then, got arrested outside Downing Street for protesting on 18 Dec 1998 when Tony Blair bombed southern Iraq, and recently on most of the London Gaza marches, wearing the white poppy. The PPU is important. The history of the PPU is important. But the future is more so. Colin would like to see our movement growing and our vital voice reach new ears. In the context of present conflict issues, war-mongering, limiting of freedoms at home and elsewhere, the work for peace is crucial. He was born and lived in Northern Ireland until he was 29 but went to Manchester to study. He wants to contribute in whichever way he can to the PPU. Colin is also a member of Anglican Pacifist Fellowship, Pax Christi and a supporter of Jews for Justice for Palestine.

Liz Szewczyk

Liz is a longstanding white poppy wearer, PPU member as well as volunteer in the PPU office. She first heard of white poppies long before she knew anything about the PPU. Whilst working at a primary school in Hackney, Liz decided to run a whole school assembly on white poppies for Remembrance Day. She expected flack, but instead parents came to me to find out more and to thank me. This was a prompt to do more. Liz found Peace Passage and has been involved ever since, mainly packing poppies but also talking about the PPU, most recently in New Zealand where she was for ANZAC Day in April 2025 and where she found white poppies on various war memorials.

Geoff Tibbs (Remembrance Project Manager)

Geoff runs the PPU's Remembrance and White Poppies campaign. When he isn't busy distributing white poppies to the thousands worldwide who wear them each year, his work focuses on building a peaceful and inclusive culture of remembrance. Prior to joining the PPU in 2019, Geoff worked on projects in the arts and voluntary sectors, including a hate crime reporting app for London and a magazine for new creative writing. Alongside working for the PPU, Geoff is a painter and a magician.

Amy Corcoran (Operations Manager)

Amy joined the PPU staff as Operations Manager in September 2023. Amy is an artist, writer and researcher who has been involved in the peace movement for the past decade, including through helping organise the first Art the Arms Fair. She's interested pacifism's intersections with freedom of movement, climate change and feminism. Amy has a background in supporting activists and analysing nonviolent resistance, as well as in psychology, human rights law, community projects and cooperative living. Her PhD - 'Protesting the Borders but on the Borders of Protest: Art Activism as Resistance to State Crime' - investigated the ways artists intervene in public space to challenge European border control policies. Amy loves overland travel, punk, animals and being out in nature (in all weathers).
