Police said the three supported hatred against Muslims and immigrants and discussed attacks on mosques or synagogues.
British police say three men have been convicted of planning to launch an attack on a mosque or synagogue in the upcoming match.
Brogan Stewart, 25, and Marco Pitzettu, and Christopher Ringrose, 34, pleaded not guilty but were ruled by jurors on Wednesday at Sheffield Crown Court. The sentencing is scheduled for July 17.
"Stuart, Pittto and Lingross were reasonably guilty of multiple terror crimes today," Detective Chief Principal James Dunkerley said in a statement.
“They are a group that advocates racist views and advocates for violence, all supporting their extreme right-wing thinking.”
In the UK debate on immigration rights, this must be a crime because of increasingly harsh remarks made by the center's left-wing Labour party in support of the far right. Commentators say Keir Starmer's recent speech said he said immigration threats to turn Britain into a "stranger island" which helps legitimize the far right-wing view that immigration is a destructive and dangerous force to the greatest extent.
The convicted far-right group is part of a telegram channel called Einsatz 14, in which they talk about the execution of former Prime Minister Rishi Sunak and torture Imams.
"Their belief is that it will surely come soon, and there will be a racial war between whites and other races," Prosecutor Jonathan Sandiford told the jurors.
Muslims and Immigration is becoming increasingly common in recent years. The conspiracy theories of Muslims and Immigration are making “great alternatives” to Western countries.
This conspiracy often involves an anti-Semitic perspective, portraying Jews as supporters of pro-migration policies aimed at undermining Western countries from within.
All three were convicted of planned terrorism and multiple gun crimes. They are found guilty of two counts of collecting information that could be useful to people preparing for terrorist acts, and Ringrose is also charged with manufacturing components for 3D printed FGC9 guns.
Prosecutors said the group was preparing for acts of terrorism when it was arrested in February 2024. Their trial began in March.
"Some of their defenses in court are that it's all fantasy, or just part of harmless chat, but all three take the actual step plan and prepare to attack innocent citizens," Dunkley said.
