The two-day hearing concerns allegations that he breached a 2021 High Court order barring him from repeating defamatory allegations against a Syrian refugee who successfully sued him.
The 41-year-old, whose real name is Stephen Yaxley-Lennon, has been charged with contempt of court after a film was shown at a protest in Trafalgar Square in July.
Robinson visited Folkestone police station on Friday, where he was remanded in custody and separately charged with failing to provide his mobile phone passcode to police under Schedule 7 of the Terrorism Act 2000.
On Saturday, thousands of his supporters gathered in central London for a protest that the political activist skipped after being detained.
Demonstrators carried placards reading “Two-tier Keir fueled the riots” and chanted “We want Tommy out” as they made their way from Victoria Station to Parliament Square.
Robinson was released on unconditional bail in July and subsequently left the country, with Adam Pyther, representing the Attorney-General, telling the High Court there was “nothing stopping him from doing so”.
Mr Justice Johnson issued a warrant for Robinson’s arrest but ordered that it not be carried out “until early October” to give Robinson time to indicate that he will attend the next hearing voluntarily or apply for a “cancellation”. of the order.
Robinson posted a video of himself arriving at Luton Airport on October 20 and said he was surprised he wasn’t arrested.
He applied to set aside the order, but his application was rejected by Judge Johnson on Friday.
