About us


We are an international programme of Transparency International situated within Transparency International UK in London.


In 2000, Transparency International UK brought together governments, defence companies, academics, and civil society organisations to consider whether circumstances had changed so that it would be possible for civil society to engage with the problem of corruption in the defence sector and national defence establishments.

Today, Transparency International Defence & Security Programme is an international programme of Transparency International situated within Transparency International UK in London.

Since 2004, we have actively engaged with the defence and security ministries and armed forces of a wide range of countries, including Colombia, Norway, Afghanistan, Bulgaria, Ukraine, the UK, Greece, Croatia and Bosnia. We have also worked directly with individuals from defence ministries, security ministries and armed forces from more than 35 nations through training programmes, research, workshops and roundtables, and high-level policy action.
