Castro ready to take on political role:
``I think Fidel is ready to take on his political role in Cuba and his historical role before the world,'' Lula said, adding that the 81-year-old ``has incredible lucidity and impeccable health.''
Castro may visit Venezuela, his friend and ally Venezuelan President Hugo Chavez said on Saturday, in what would be the 84-year-old Castro's first visit abroad in at least four years.
