Venezuelan President Hugo Chavez arrived in Havana early Wednesday for medical treatment, Cuban state media reported, quoted by CNN. It’s unclear whether the trip is a sign of a relapse of the cancer that has ailed him or is for a check-up. Venezuela’s national assembly on Tuesday voted to grant Chavez permission to travel to Cuba for the treatment, the state-run AVN news agency reported. In October, Chavez was re-elected to a new term after having received treatment for cancer in preceding months.Between June 2011 and May 2012, he underwent cancer treatment in Cuba, raising speculation about his political future and about a possible successor, especially when he named 10 people to his inner circle of advisers, known as the Council of State. But he declared himself cancer-free in July and went ahead with his campaign. The status of his health, however, has been a closely held secret, and some individuals who claim to have insider knowledge say the president is in much worse condition than he publicly lets on.
