Thomas is alleged to have used his social media platform to livestream himself from the English Channel at around 16:30 BST on 22 September, broadcasting to a large audience, the court heard.

He is accused of slashing a boat that had been used by migrants, which was adrift in the sea, while a rescue crew member was on board.

He is also alleged to have said "this is what needs to happen" and "this is England, this isn't France any more".

Simon Pentol KC, defending, had proposed a "package of bail conditions" as an alternative to Thomas being remanded in custody and described the allegation against his client as "politically charged and fundamentally flawed".

On his decision to refuse bail, the Judge James Newton-Price KC, said: "I am not concerned with the political issues or motivations in this matter and I put them aside in deciding this matter."

A handful of supporters waited outside the court to hear the outcome of the hearing.
