Common Principles for Support to Parliaments

The Common Principles for Support to Parliaments set out the fundamental principles for planning and implementing programmes to strengthen parliaments. They were first developed in 2014 by a group of parliaments and partners convened by the IPU and have been widely endorsed around the world.

Parliamentary support should:

  • Be guided by the needs of parliaments
  • Take account of the social, economic and political contexts of individual parliaments
  • Aim for sustainable outcomes
  • Include all political tendencies
  • Be grounded in international standards
  • Address the needs and potential of women and men equally
  • Use local and regional expertise
  • Use effective coordination and communication
  • Guarantee ethical and responsible conduct by partners

Tenth anniversary

2024 marks the 10th anniversary of the Common Principles. To celebrate this milestone, the IPU is planning special events at the 149th IPU Assembly in October 2024. Parliaments and organizations around the world are invited to join the commemoration.

Show your dedication to parliamentary development by hosting an event leading up to the anniversary or marking it online. This toolkit provides a wealth of resources to help you celebrate, including materials to promote the Common Principles and parliamentary development more broadly.
