Embratel Participacoes, Brazil's largest long-distance operator, accused the country's top three fixed-line phone companies of unfair practices after a report this weekend said the groups were colluding to raise phone rates. Embratel said in a statement it had reiterated an earlier request before Brazil's antitrust authorities to prevent its sale to three companies, which are part of a group called Calais Participacoes seeking to outbid Mexico's Telmex for Embratel.
