Ms Cutter, 23, was described by prosecuting barrister Barnaby Jameson as an “active member” of National Action at Monday’s hearing.
National Action was proscribed as a terrorist organisation in December 2016, after a series of incidents including the praising of the murdered of Labour MP Jo Cox.
Ms Cutter, who had participated in the Miss Hitler beauty pageant as Miss Buchenwald, had initial denied membership of National Action until footage emerged showing her standing with other members giving a Nazi salute behind a banner that read “Hitler Was Right”.
On Monday, jurors were shown messages in which Ms Cutter had joked about using a Jew’s head as a football and gassing synagogues.
The court also heard that Ms Cutter had made an unsuccessful attempt to recruit a 15-year-old girl, in what Mr Jameson described as a targeted recruitment “pattern” by Ms Cutter and her then boyfriend Mark Jones.
Jones, 25, a former organiser for National Action’s London branch, accepted having delivered a Nazi salute and holding a National Action flag in the execution room at Buchenwald in 2016.
Mr Jameson said that after National Action’s proscription, Jones produced propaganda for two splinter groups – NS131 and Scottish Dawn – both of which have since been banned.
Garry Jack, 24, described as an “active and committed member” of National Action, had previously been given a suspended jail term for racially-aggravating placing stickers in Aston University, while Connor Scothern, 19, was described by another leading member of National Action as having “driven himself into poverty” travelling to meetings and printing 1,500 stickers calling for a new ‘Final Solution’.
Director of public prosecutions, Max Hill QC, told Radio 4 on Monday: “They are diehards in the way they think.”
Mr Hill continued: “They hark back to the days of not just antisemitism, but of the Holocaust, the Third Reich in Germany, and they take their mindset from those extreme Nazi groups and latterly neo-Nazi groups in Germany.”
