The UK Digital, Culture, Media and Sport Committee wrote to CEO Mark Zuckerberg on 20th March 2018 to summon him to explain how social media data is being used (or misused) for political advert targetting.
A Facebook spokesperson has said they will be sending its CTO or Chief Product Officer to answer questions instead.
“We have responded to Mr Collins and the DCMS and offered for two senior company representatives from our management team to meet with the Committee depending on timings most convenient for them.”
On 17th March, reports in the Observer of London and the New York Times claimed Cambridge Analytica, a UK political agency, was able to purchase data about 50 million Facebook users in 2015 to use for targeted political advertising.
