ROME (Reuters) - Stellantis will extend the stoppage of car production at its Italian Mirafiori plant by a further two weeks, until Jan. 20, the head of the FIOM-Cgil trade union at the site said on Thursday.

FIOM's Gianni Mannori said the decision - first reported by daily MF - had not yet been made official by the company.

A spokesperson for Stellantis did not immediately respond to a request for comment.
