Hugo Chávez talked of a successor for the first time after admitting Sunday that he would return to Cuba for more cancer treatments. The Venezuelan president only returned from his last round of cancer treatments Friday. Chavez said that it is “absolutely necessary, absolutely essential,” that he returns for more surgery. Supporters should vote for current Vice President Nicholás Maduro should anything happen to Chávez in the course of treatment, the leader said, speaking from the Venezuelan capital. Chavez has been battling unspecified cancer in his pelvic region since June 2011.
