UK and Canada unite to demand Mark Zuckerberg answers questions

Joint hearing will try to force Facebook chief to appear over Cambridge Analytica scandal

The UK and Canadian parliaments are joining forces in an attempt to force Mark Zuckerberg to answer their questions over Facebook's role in the Cambridge Analytica scandal.

The House of Commons digital, culture, media and sport select committee has announced its intention to hold a highly unusual joint hearing with its Canadian equivalent in an attempt to pressure the social network's chief executive into appearing in front of parliament.
