ROME (Reuters) - Giovanni Castellucci could offer his resignation as chief executive of infrastructure group Atlantia ATL.MI at an extraordinary board meeting called on Tuesday, a source said on Monday.

It will be up to the board to take a final decision on the matter.

Atlantia, controlled by the Benetton family, runs Italian motorway group Autostrade per l’Italia which became embroiled in a legal battle following the collapse of a bridge last year which killed 43 people.
