Iran's Majlis Speaker Ali Larijani is scheduled to leave Tehran for Serbia on the first leg of his tour to three European countries, Press TV reported.
Larijani will leave the Iranian capital on Sunday for a two-day visit to Serbia to hold talks with the country's senior officials.
The Iranian official will then head to Switzerland to attend the 129th Inter-Parliamentary Union (IPU) Assembly in Geneva where he is scheduled to deliver a speech.
The 129th IPU assembly will take place from October 7 to 9 in Geneva. The IPU Assembly is the principal statutory body that expresses the views of the Inter-Parliamentary Union on political issues. It brings together lawmakers to study international problems and make recommendations for action.
During the assembly parliamentarians will discuss the role of parliaments in protecting the rights of children, in particular unaccompanied migrant children, and in preventing their exploitation in situations of war and conflict.
They will also discuss the contribution of parliaments towards a nuclear-weapon-free world and how to move toward risk-resilient development, while taking into consideration demographic trends and natural constraints.
The Majlis speaker plans to pay a two-day visit to Croatia after the IPU meeting to meet with Croatian officials.
A delegation of Iranian parliamentarians left Tehran for Switzerland on Saturday to attend the IPU.
The IPU was established in 1889. The national parliaments of 162 countries are members of the IPU, and 10 regional parliamentary assemblies are associate members. The IPU has permanent observer status at the United Nations and general consultative status with the Economic and Social Council.
