Activists and former political prisoners in Paraguay have staged a demonstration against a proposal to repatriate the remains of former military ruler Gen AlfredoStroessner.
As an army colonel he played a prominent part in the uprising which overthrew Gen AlfredoStroessner in 1989, delivering the news that he was under arrest.
In his inaugural speech, Mr Cubas made a good impression on a country where democracy has struggled to put down roots since General Alfredo Stroessner's 35-year dictatorship ended in 1989.
Party colleagues described him as an "efficient" politician who advocated a fresh start for the Colorado Party, which had been an ally of military ruler AlfredoStroessner, who ruled from 1954 to 1989.
One of his grandsons, a senator also called Alfredo, said efforts were continuing to have Gen Stroessner's remains laid to rest in his country of birth.
