Mexico's election officials have began the official count of ballots cast in Sunday's close presidential election. In unofficial results, the conservative candidate Felipe Calderon is ahead by a slim margin. But Mexico requires a simple majority to win the presidency.
Leftist candidate Andres Manual Lopez Obrador has protested the unofficial results, calling for a recount of every ballot cast. He is now charging fraud, claiming the electoral body is manipulating ballots so Calderon can win.
