A jury at Birmingham Crown Court in central England found 22-year-old Adam Thomas and 38-year-old Claudia Patatas guilty of being members of National Action. A third defendant, Daniel Bogunovic, was also convicted of membership in the banned group. Three others pleaded guilty before the trial started.
During the trial, jurors were shown photos of Thomas holding his baby son—who was given the middle name Adolf—while wearing the white robes of the Ku Klux Klan.
Prosecutors said the defendants attended meetings of the banned group and exchanged WhatsApp messages praising the Nazis’ murder of Jews.
The government banned National Action in 2016 after Labour Party lawmaker Jo Cox was murdered by a far-right extremist. Ten people have now been convicted of membership in the group, including a British soldier who had served in Afghanistan.
British police say the threat from violent far-right groups is growing, with four plots foiled in the year to March.
All six defendants are due to be sentenced on December 14.
