Mexico’s centre-right government on Tuesday admitted that there was a ”latent threat” of drug money finding its way into the country’s political campaigns and warned that the country’s police forces had been ”infiltrated” by powerful cartels.

In an address to Congress, Juan Camilo Mourińo, a government minister, said: ”The risk of drug Money in campaigns is, of course, a latent risk.” He added: ”The police are infiltrated and as long as they are infiltrated we cannot, fully, guarantee security or secure people’s confidence.”
