Campaigning between the two remaining rivals in Senegal’s presidential election second round runoff ended on Friday after weeks of rallies.
Opponents claimed current leader, 86-year-old Abdoulaye Wade, would break the constitution if he won a third term in Sunday’s vote.
Despite winning the most votes in the first round, supporters of the dozen other opposition candidates who took part were expected to throw their support behind Macky Sall, a former prime minister in the second round.
Sall also has the support of grammy award-winning musician Youssou N’Dour, who has promised a comeback concert if Sall wins. N’Dour was himself a presidential hopeful.
Wade’s promised to step down within three years of his third term, once expensive infrastructure projects, including a new airport for the capital Dakar and new toll highways, are complete.
Senegal has had only three leaders since it gained independence from France in 1960.
