The chair of the digital, culture, media and sport committee Damian Collins has asked the billionaire tech entrepreneur to provide examples of adverts purchased by accounts linked to Russia, how much such ads cost and how many views they got, among other things.
The request comes as the group of MPs investigates the effect of fake news on politics and as US lawmakers investigate the extent of Russia's influence on the election of Donald Trump as President last year.
Here's his letter in full:
I am writing to you to request information regarding the use of Facebook advertising and pages by Russian-linked accounts in the lead up to, and during, the 2016 referendum on the UK's membership of the European Union and the 2017 British General Election.
As you may be aware, the House of Commons Select Committee for Digital, Culture, Media and Sport is currently undertaking an inquiry into the phenomenon of fake news, Part of this inquiry will focus on the role of foreign actors abusing platforms such as yours to interfere in the political discourse of other nations. It is for this reason that I am requesting that Facebook provides to my committee details relating to any adverts and pages paid for, or set up by, Russian-linked accounts.
We would politely request the following:
I believe that the information that I have requested is in line with that already supplied by Facebook to several United Stated Senate Committees,m including the Senate Intelligence Committee, in relation to the 2016 US Presidential election.
I look forward to your response, and receiving the information that I have requested.
