A British neo-Nazi accused of terrorism offences plotted to kill non-Aryans in a cyanide attack, a court has heard.

Mark Colborne, 36, appeared at Westminster Magistrate's Court charged with engaging in conduct in preparation of terrorist acts following his arrest on 3 June.

He was charged after officers from Hampshire Constabulary and South East Counter Terrorism Unit searched the home he shared with his mother in Sholing, Southampton.

Colborne spoke only to confirm his name, age and address. No indication of a plea was given.

He is also accused of researching techniques and possessing material to help produce lethal poisons and explosives and of expressing intent to kill people of various ethnicities.

The judge warned Colborne that he faces a lengthy prison sentence if he is convicted.

Colborne was refused bail and remanded in custody until his next appearance in court on 18 July.

A Hampshire police spokesman said: "This charge follows an arrest and search at an address in Butts Road on 3 June this year. It is not part of a wider investigation and there is no threat to the local community."
