 Telecom Italia TIM is set to appoint General Manager Pietro Labriola as CEO on Friday as the former phone monopoly weighs a response to a takeover approach by U.S. private equity investor KKR. Labriola, a veteran TIM executive who has run TIMs Brazilian operations for the last three years, was promoted to general manager in November, when former CEO Luigi Gubitosi stepped down following a string of profit warnings.
