Artem Lobov has launched High Court proceedings against Conor McGregor over an alleged barrage of harassing, intimidating and defamatory posts on social media about the Dublin-based retired Russian MMA fighter.

Mr Lebov claims that the most damaging post about him on Mr McGregor's Twitter account, @TheNotoriousMMA, is where he is allegedly referred to in a song sung by Mr McGregor as being a "rat".
