The committee repeated its call for Facebook chief Mark Zuckerberg to give evidence
The UK faces a "democratic crisis" due to the spread of "pernicious views" and the manipulation of personal data, a parliamentary committee is set to warn.
The Digital, Culture, Media and Sport (DCMS) Committee has been investigating disinformation and fake news following the Cambridge Analytica data scandal.
In its first report it will suggest social media companies should face tighter regulation.
It also proposes measures to combat election interference.
The report warns that the "relentless targeting of hyper-partisan views, which play to the fears and prejudices of people, in order to influence their voting plans" is a threat to democracy.
