A group of Brazilian telecoms operators are now ready to bid for rival TIM ParticipaA A es SA, a source with knowledge of the situation said, after the group's leader, Oi SA, got the go-ahead to sell its Portuguese business. However, top management at Telecom Italia SpA, TIM's majority owner, is preparing for a meeting with Brazilian officials next week to put out feelers before deciding whether to turn the tables and make their own bid for Oi, two other sources familiar with the plans said.
