Facebook boss Mark Zuckerberg has been threatened with a summons forcing him to appear before parliament the next time he is in the UK if he does not present himself voluntarily.
The billionaire tech tycoon has so far resisted attempts by the Digital, Culture, Media and Sport Select Committee chair Damian Collins to have him give evidence, instead sending his chief technology officer Mike Schroepfer.
In a letter dated today, Collins told Facebook's head of public policy Rebecca Stimson the committee was not happy with Schroepfer's appearance, saying his evidence "lacked many of the important details that we need". The letter goes on to detail 40 points on which Zuckerberg's deputy failed to answer questions, relating to the recent harvesting of millions of users' data, sufficiently.
As a result, Zuckerberg has been invited to Westminster once again, with Collins suggesting an appearance could take place during another evidence session, before the European Parliament.
Collins wrote: "It is worth noting that, while Mr Zuckerberg does not normally come under the jurisdiction of the UK Parliament, he will do so the next time he enters the country. We hope he will respond positively to our request, but if not the committee will resolve to issue a formal summons for him to appear when he is next in the UK."
