Tests show Argentina's late strongman Juan Domingo Peron did not father a woman who claims to be his daughter, lawyers for the president's widow say.
The Peron era is still regarded fondly by many Argentines
Martha Holgado, 72, is fighting to be recognised as Peron's only descendant.
Lawyers for Peron's widow said a DNA test on his remains was negative, but Ms Holgado rejected this, saying she was waiting for more test results.
Peron's body was reburied in a new mausoleum last month amid clashes between rival groups of supporters.
A court ordered that DNA samples be taken when his remains were disinterred prior to reburial and final test results are still to be made public.
A lawyer for Peron's widow, Maria Estela Isabel Martinez de Peron, said the private test showed no relation between the ex-president and Ms Holgado.
But Ms Holgado told Argentine media that there was something suspicious about these results.
"I was born Juancito's daughter and will die Juancito's daughter," she told the Clarin newspaper.
She says the late leader fathered her in an extra-marital relationship during his marriage to his first wife.
Peron, who died in 1974, is still revered by many Argentines who see him as a champion of the country's poor.
