Before the 31st G8 summit at Gleneagles , Scotland , in 2005 , Tutu called on world leaders to promote free trade with poorer countries and to end expensive taxes on anti-AIDS drugs . In July 2007 , Tutu was declared Chair of The Elders , a group of world leaders to contribute their wisdom , kindness , leadership and integrity to tackle some of the world 's toughest problems . Tutu served in this capacity until May 2013 . Upon stepping down and becoming an Honorary Elder , he said : " As Elders we should always oppose presidents for Life . After six wonderful years as Chair , I am sad to say that it was time for me to step down . " Tutu led The Elders ' visit to Sudan in October 2007 – their first mission after the group was founded – to foster peace in the Darfur crisis . " Our hope is that we can keep Darfur in the spotlight and spur on governments to help keep peace in the region , " said Tutu . He has also travelled with Elders delegations to Ivory Coast , Cyprus , Ethiopia , India , South Sudan and the Middle East
