Liberal Democrat MP Christine Jardine has warned "democracy is at risk" if the report by the Digital, Culture, Media and Sport Committee into disinformation and fake news is ignored.
Ms Jardine said:
"This report is a watershed moment for our democracy. Evidence of disinformation and voter suppression – particularly during the EU referendum – are deeply disturbing.
"We must demand better. People deserve an open, tolerant and transparent politics. The digital age should aid that, not harm it.
"Our democracy is at risk if the recommendations of this report are ignored. There is also now a legitimate case for a judge-led inquiry into what has gone on and those who have been found of breaking electoral law must face repercussions.
“Meanwhile, given the evidence uncovered, the people must be given the final say on Brexit and an opportunity to remain in the EU."
