Second Expert Roundtable on the Common Principles for Support to Parliaments - Proactive parliaments: Bolstering self-development
The Common Principles for Support to Parliaments aim to enhance the quality and effectiveness of Parliamentary support programmes. Developed by a small working group and widely drawing on inputs from parliaments and other organizations in identifying good practice to guide parliamentary strengthening, the Common Principles are a resource owned by and serving the entire parliamentary community. They were adopted by the 131st IPU Assembly in October 2014 and have since received the endorsement of over 115 parliaments and organizations.
To further implement the Common Principles, user-friendly tools that facilitate their application are needed. To inform this objective, a series of Roundtables have been organized involving parliaments and partner organizations. The First Roundtable focused on Common Principle 3: Parliamentary support aims for sustainable outcomes. This Second Expert Roundtable is dedicated to strengthening parliamentary governance over their own development through their increased engagement in the definition and realization of development priorities.
Through interactive discussions, the Roundtable will inform the production of a Guide for parliaments and partners that will help enable more proactive engagement by parliaments. It will map out suggestions for the infrastructure and processes needed to this end and provide parliaments and support partners with a transparent set of criteria on which to build support relationships, resulting in stronger partnerships and more effective and sustainable outcomes.
