Telecom Italia said yesterday it would sell only part of its majority stake in Telecom Argentina and the rest once the regulator approved its full sale to New York-based fund Fintech, owned by Mexican billionaire David Martnez. The Italian phone group had agreed to sell its controlling stake in Telecom Argentina holding company Sofora to Fintech for US$960 million almost one year ago, but the Argentine telecoms regulator SECOM has been slow to approve the deal.
