A 2011 poll by the Reputation Institute of more than 50,000 people in 25 different countries found #1 Nelson Mandela and #2 Roger Federer to be the most respected and trusted people in the world.
Roger Federer has just arrived in South Africa to inspect some of his foundation's projects.
He hopes to meet with #1 Nelson Mandela while he is there.
