The European Commission's energy czar, Miguel Arias Cañete, and his family will likely face close scrutiny from the European Parliament's committee set up to look into Panama Papers leak, said Werner Langen, the committee's chairman.

Langen told POLITICO that "Cañete would possibly be part of that" list of individuals who would be called to face further questions over their links to offshore shell companies.

The Spanish commissioner's wife appeared in a leak of some 11 million files from the Panamanian law firm Mossack Fonseca.

"I assume my fellow Parliamentarians will request it," Langen said today. "In this case, we would probably hear from his family."

Former antitrust Commissioner Neelie Kroes "also belongs to that [list]," Langen continued, after Kroes' name was found among recently leaked documents about offshore companies in the Bahamas.

Parliamentarians in the committee are in the process of compiling names of individuals who would be called to face questions in Brussels over the use of offshore companies or funds. It's unclear when the list will be finalized and published.
