Facebook CEO Mark Zuckerberg will meet with leaders of the European parliament in a closed-door meeting next Tuesday about the data protection scandal that has engulfed his company.

Even though his visit had been announced, it was left unclear exactly when Zuckerberg would visit the European Union legislature.

The EU and British parliaments have been calling for Zuckerberg to appear before them for weeks ever since it emerged that a company, political consultants Cambridge Analytica, had been allowed to misuse the data of millions of Facebook users.

The EU meeting however is set to be private with the leaders of the political groups and a justice and civil rights expert. Many in the European Parliament had been calling for a public hearing.
