Delgado

Among the candidates in Chihuahua state is Silvia Rocío Delgado, a one-time lawyer for the notorious “El Chapo” Guzmán, now serving a life sentence in the United States for narcotics trafficking, murder and other crimes.

“There shouldn’t be a stigma” for having represented El Chapo, Delgado told Univisión Noticias.

But in Sunday's rather unique election – the first of two votes by which Mexicans will choose the country's entire judiciary by direct ballot – Silvia Delgado is not an ordinary candidate.

Silvia Delgado has not been convicted of any crime, is not facing any charges and is not under investigation – whether over her links to El Chapo or anything else.

As well as Ms Delgado, the list includes a candidate with a drug trafficking conviction and another facing accusations of orchestrating violence against journalists.
