French industry minister Arnaud Montebourg, and junior minister Fleur Pellerin - whose remit includes the digital economy - have asked representatives of the social networking site to give "clear and transparent explanations" regarding recent privacy concerns, according to Reuters.
Facebook representatives will reportedly appear before the Commission nationale de l'informatique et des libertés (CNIL) later on Tuesday (September 25), following numerous claims that private messages had been appearing on some users' public timelines.
The alleged problem was said to have mainly affected users in France, where the Timeline profile format was recently rolled out universally, and in the United States.
Facebook denied that any private messages had been leaked in a statement on Monday evening (September 24), but users have continued to allege that messages they believed were private have appeared in their timelines.
"A minority of users were worried after seeing messages they thought to be private appearing on their Timelines," a spokesperson for Facebook France said, while a source told BBC News that there was "no way" that private and public data streams could get muddled up.
