TUNISIA-VOTE-ESSEBSI

Tunisian special forces stand guard in a vehicle as Tunisian presidential candidate and former prime minister Beji Caid Essebsi , 88, gives a speech during his presidential election campaign tour on December 17, 2014 in the Kef region, northwest of the capital Tunis, as Tunisians prepare to vote on the weekend in the second round of the presidential election, capping off four years of a sometimes chaotic transition since their country sparked the Arab Spring. Essebsi's secular Nidaa Tounes party won parliamentary elections in October and he has emerged as the clear favourite to be Tunisia's next leader, though with reduced influence after constitutional changes stripped the president of many powers.
