In view of ongoing and recent contestations between the president and prime minister, and president and legislature in Tunisia and in Sri Lanka, International IDEA’s Constitution-Building Programme organised a webinar on the ‘Value and Perils of Semi-Presidentialism in Transitional Contexts’ on 2 August 2021. Consititution-building experts also discussed Nepal—though it does not have a semi-presidential system—because of its parliamentary system that has recently faced political instability in similar ways as Tunisia and Sri Lanka.
