TIM said Gallazzi, 58, will join the board as an independent director to replace Renault boss Luca de Meo, who stepped down in September.

Gallazzi also sits as an independent director on the board of Italian broadcaster MediaforEurope, of which Telecom Italia's top shareholder Vivendi is also an investor.

Telecom Italia added that it has kicked off the process to select a director to replace Vivendi's representative Frank Cadoret, who quit TIM's board this month. The next board meeting is scheduled on Dec. 15.

A potential candidate for the role is Italy's telecoms lobby head Massimo Sarmi, whose appointment is favoured by Vivendi.
