The body of five-time F1 World Champion Fangio was exhumed by court order in August in order to test his DNA and determine the validity of two men's paternity claims, the men being Oscar Espinoza and Ruben Vazquez.

On Wednesday, Judge Rodrigo Cataldo of Mar del Plata, Argentina, has announced that Espinoza, who had a close relationship with Fangio for several years and himself had an extensive racing career, is a biological son of the F1 legend.

Vazquez's case is expected to be resolved in the coming days.

Fangio was never married nor had any other recognised children in his lifetime - although he had a lengthy relationship Andrea Berruet, Espinoza’s mother.

Vazquez, meanwhile, claims that his late mother Catalina Basili confessed in 2005 that he was Fangio’s son, the product of a relationship she had had with the driver in the 1940s.
