Former Uruguayan president Jose "Pepe" Mujica casts his vote in the country's presidential election, in which a left-wing history teacher is tipped to win power after five years of centre-right rule. Polls show security topping the concerns of voters in the tiny country of 3.4 million people, which has faced an increase in drug-related violence in recent years. Mujica who is undergoing cancer treatment, remains actively involved in politics but says at the polling station that "it may be my last vote." IMAGES AND SOUNDBITES
