(Reuters) Venezuela’s Hugo Chavez said on Saturday that his cancer had returned and he would undergo another operation in the coming days, and for the first time the president named a successor if anything happened to him.

The news was a big blow for supporters of the 58-year-old socialist leader, who elected him in October to a new six-year term in office. Twice since mid-2011 Chavez has said he was cured, and then had to have more surgery.
