A BT Group Plc executive has called for the United States to require its telecommunications companies to allow access to their networks at regulated prices, similar to rules in place in the United Kingdom, the Financial Times reported on Sunday. Bas Burger, president of the British company's Americas unit, told the newspaper that a lack of regulation has hampered competition in the United States, where AT&T Inc and Verizon Communications Inc control about 80 percent of the telephone and broadband lines used by homes and businesses.
