Macky Sall may be 30 years younger than his former boss, President Abdoulaye Wade, whom he defeated in a run-off election for Senegal's top job. But he does not lack political pedigree.
The 50-year-old geologist, who was brought up in a poor family, served as Mr Wade's prime minister between 2004 and 2007 and before that held the interior and mines portfolios.
