The man accused of murdering Labour MP Jo Cox was brought before a senior judge at the Old Bailey under the "terrorism protocol".
Thomas Mair, 52, is accused of shooting and stabbing Cox, 41, outside her constituency surgery in Birstall, near Leeds, last Thursday.
He is charged with murder, grievous bodily harm, possession of a firearm with intent to commit an indictable offence and possession of an offensive weapon.
Mair, from Birstall, made his first crown court appearance before Justice Sweeney via video link from top security Belmarsh prison.
During the brief hearing, he spoke only to confirm his name - unlike his first appearance at magistrates' court when he declared: "Death to traitors, freedom for Britain."
Grey-bearded Mair sat with his arms folded beside a prison officer. He wore beige trousers and a white long-sleeved t-shirt.
There was no application for bail and he was remanded in custody.
He will appear at the same court for a preliminary hearing before Justice Saunders at 10am on Thursday.
Cases under the terrorism protocol are managed by senior judges, usually sitting at the Old Bailey.
Justice Saunders is expected to set a timetable for Mair's case at the next hearing.
