Pansa, currently chairman of TIM's submarine cable unit Sparkle, secured nine votes out of 14 at a board meeting on Wednesday, sources familiar with the matter told Reuters earlier in the day.

The board representative of TIM's second-biggest investor, state lender CDP, voted in favour of Pansa, a source said.

He prevailed over Luciano Carta, a former chairman of Italian defence group Leonardo, who was backed by TIM's leading investor Vivendi.
