The winner of the July 1 presidential election will change Mexico’s anti-drug strategy, British journalist Ioan Grillo said in an interview with Efe.

Grillo, whose book “El Narco: Inside Mexico’s Criminal Insurgency” (Bloomsbury Press, 2011) comes out this week in France, criticized the security policy implemented by President Felipe Calderon, whose term ends in December.

“I believe that the narcos, as a whole, are not being destroyed by the force of arms of the current government” in Mexico, Grillo, a freelance writer who has covered Mexico for 11 years for a variety of U.S. and British media outlets, said.

The book, which examines the history, structure and future of Mexico’s drug cartels with a journalistic approach, is different from other works that focused on leading drug traffickers or cartels, looking at the social aspects of a phenomenon that has been incubated for nearly a century.
