Former Fianna Fáil TD for Kildare North Frank O’Rourke is suing Twitter and Facebook for hosting posts in the run-up to last February’s general election which he claims were highly defamatory and based on complete falsehoods

Former Fianna Fáil TD Frank O’Rourke has been granted permission by the High Court to add 'persons unknown' to defamation proceedings he has brought over social media posts made in the run-up to last year's general election.

The court heard an internal investigation at Facebook Ireland tried to locate the post or who was responsible for it but was unable to do so.
