MEXICO CITY (AP) — A dispute over control of hundreds of millions of dollars’ worth of wireless frequencies has erupted into an ugly, personal feud between Mexico’s government and one of its most influential media companies.

The head of broadcaster MVS Communications and some of the top officials in President Felipe Calderon’s administration accused each other Wednesday of lying about the government’s reason for withdrawing MVS’s right to frequencies in a bandwidth used by the newest generation of mobile devices.
