(Telecompaper) Italian state lender Cassa Depositi e Prestiti (CDP) is considering the possibility of selling its 50 percent stake in wholesale operator Open Fiber to Telecom Italia (TIM), which would issue shares in return for the holding, according to unnamed sources cited in Il Messaggero. The move would allow TIM to merge its fixed network with that of Open Fiber with a view to avoiding infrastructure duplication, said the report, adding that CDP executives have discussed the transaction with TIM's leading investor Vivendi.
