A/RES/54/261 Page 4 B 6. The four round tables will have at least 40 seats each and will be chaired by a head of State or Government. 7. The chairpersons of three of the round tables will be from the three regions not represented by the two Co-Chairpersons of the Millennium Summit. Those three chairpersons will be selected by their respective regional groups in consultation with the President of the General Assembly. The choice of chairperson of the fourth round table will be subject to further consultations. 8. Following the selection of the chairpersons of the round tables, each regional group will determine which of its members will participate in each round table, ensuring that equitable geographical distribution will be maintained, allowing for some flexibility. The chairpersons of the regional groups will communicate to the President of the General Assembly the list of countries from their respective regions that will participate in each round table. Member States are encouraged to be represented at the round tables at the level of heads of State or Government. 9. All four round tables will cover the same overarching theme and sub-themes.
