Polls opened Sunday in the second round of Tunisia's first free presidential election, in the final leg of an at times bumpy four-year transition from dictatorship.
The runoff pits 88-year-old favourite Beji Caid Essebsi, leader of the anti-Islamist Nidaa Tounes party, against incumbent Moncef Marzouki, who held the post through an alliance with the moderate Islamist movement Ennahda.
Polls are due to close at 1700 GMT and the result is to be announced between Monday and Wednesday.
