Unofficial polls in Senegal suggest the presidential election might have to go to a second round.
The two main rivals, the incumbent President Abdoulaye Wade and Macky Sall appear to be neck and neck in a vote that was mired in controversy even before the polling stations opened.
The 85-year-old president sparked weeks of violent street protests by announcing he would stand for a third stint in charge, even though the constitution only allows a president two terms.
His main rival is a former Wade protege and fellow liberal Macky Sall, who was prime minister before falling out with the President in 2008.
Senegal’s top legal body had approved Wade’s candidature, sparking the street clashes. He had argued that the two-term limit did not apply because it was brought in after he had come to power and so his first term did not count.
