Former Canadian Prime Minister Paul Martin, drawing on his personal experience with the Group of 20 finance ministers as well as the G-8, has proposed a new informal grouping that he calls an “L-20,” with the “L” signifying that it is restricted to leaders. The L-20 would build upon the G-8’s original strengths of informality and flexibility to provide a consultative forum on issues such a climate change, global health, and conflict management.
