Mexicos government may send to the Senate as soon as Friday so-called secondary laws that lay out the fine print of a reform aimed at boosting competition in the telecommunications sector, a top lawmaker said on Thursday. The secondary laws will flesh out a constitutional overhaul approved last year to open up the countrys phone and TV industries, which are dominated by billionaire Carlos Slims America Movil and the countrys No. 1 broadcaster, Televisa. Its very likely tomorrow the telecommunications secondary laws reach the Senate, Emilio Gamboa, Senate leader for the ruling Institutional Revolutionary Party told local radio.
