Chavez foes say his absence a security risk

CARACAS (Reuters) - Venezuela's opposition said on Saturday President Hugo Chavez's prolonged convalescence from cancer in Cuba put the country's security and sovereignty at risk and it stepped up calls for him to delegate his powers.

"It is clear Chavez does not have the capacity to fully exercise his power ... This is a very dangerous, nefarious precedent," Roberto Enriquez, national president of the COPEI Christian Democrat opposition party, told reporters.
