The 11th Session of the Conference of the States Parties (COSP11) to the UN Convention against Corruption (UNCAC) will take place on 9–13 December 2025 in Doha, Qatar. As the world’s largest anti-corruption gathering, COSP brings together governments, international organizations, and civil society to advance global cooperation against corruption and review progress in implementing UNCAC - the only legally binding universal anti-corruption instrument.
International IDEA will participate in COSP11 with a strong focus on political finance transparency, a critical yet often overlooked dimension of the global anti-corruption agenda. Through research, policy assistance, and global advocacy, International IDEA supports countries in strengthening regulations on political donations, campaign spending, reporting and disclosure, and oversight - key pillars for preventing undue influence and safeguarding democratic integrity.
During COSP week, International IDEA will be on the ground in Doha, contributing to discussions and sharing experiences from around the world. We will co-organize two side events on political finance reforms, and we will also deliver a general statement during the plenary session.
We look forward to engaging with anti-corruption experts, partners, and practitioners in Doha as we work together to advance political finance transparency and strengthen democratic resilience worldwide.
Please see the additional information on our statements and side events below.
