Tommy Robinson has been charged under the Terrorism Act after handing himself in at a police station in Kent.
Robinson, whose real name is Stephen Yaxley-Lennon, is accused of refusing to give police the pin number to his mobile phone in Folkestone on July 28.
The 41-year-old, of no fixed address, was charged at the town’s police station earlier today.
He has been bailed to appear at Westminster Magistrates’ Court on November 13.
Robinson is also facing potential jail time for alleged contempt of court and is due to appear at Woolwich Crown Court on Monday for a two-day hearing.
He remains in custody at the direction of the High Court over that allegation.
A High Court judge had issued a warrant for Robinson’s arrest after he failed to appear for a contempt of court hearing at the end of July.
He left the country the day after leading a protest in central London and hours after being released on unconditional bail by Kent Police, who arrested him at the Channel Tunnel in Folkestone under Schedule 7 of the Terrorism Act 2000.
The Act provides police officers with unique powers to examine people who pass through the UK’s borders.
The development comes as the Metropolitan Police prepares for thousands of supporters to descend on London and march to Whitehall tomorrow.
The march, under the banner “Uniting the Kingdom”, will be met with a counter-protest from Stop the War campaigners.
