The man charged with the murder of Labour MP Jo Cox has given his name in court as "Death to traitors, freedom for Britain".

The defendant was also charged with grievous bodily harm, possession of a firearm with intent to commit an indictable offence and possession of an offensive weapon.

Mair wore a grey jumper, tracksuit bottoms and black shoes and was handcuffed to a guard in the dock during the hearing, the Press Association reports.

He did not reply when asked to confirm his address and date of birth.

The defendant was not required to enter a plea at today's hearing.

Deputy Chief Magistrate Emma Arbuthnot ordered that he be remanded in custody until his next appearance, at the Old Bailey on Monday.

He will be held at Belmarsh Prison, and Ms Arbuthnot suggested that a psychiatric report should be prepared, saying: "Bearing in mind the name he has just given, he ought to be seen by a psychiatrist."

Cox was fatally injured outside her constituency office on Thursday. 

A 77-year-old man who tried to help her was also injured. He remains in hospital in a stable condition.
