In a letter to the chief minister, MNF general secretary Zosangliana alleged the Health, Labour and Employment, and Trade and Commerce Minister issued drug licence to his under-aged son.
Rampanmawia, a Myanmarese national and a drug trafficker, was using that drug licence to smuggle pseudo-ephedrine from India to Myanmar, he said in the letter.
"Rampanmawia was arrested by the state Excise and Narcotics department last year in connection with pseudo-ephedrine, a precursor for illicit manufacturing of Methamphetamine," he said.
