Chavez's condition improves: Minister

CARACAS (AFP) - The health of Venezuelan President Hugo Chavez has evolved in a "favourable" way in recent days, though he still requires treatment for respiratory failure, Communications Minister Ernesto Villegas said.

"Despite his delicate health state since his complex surgery on Dec 11, his general health has improved in recent days and the president is in strict compliance with his medical treatment," Mr Villegas said in a statement broadcast on radio and television.

Earlier on Sunday, however, former vice-president Elias Jaua said the leader is "fighting for his life" after cancer surgery in Cuba,

"The situation is complex and delicate, but it is true that Hugo Chavez has fought and is fighting for his life," Mr Jaua said during a meeting in Caracas of the ruling United Socialist Party.
