Two neo-Nazis, who had given their child as a middle name Adolf, in tribute to Hitler, were sentenced on Tuesday to up to six and a half years in prison for belonging to a far-right terrorist group banned at United Kingdom.

Adam Thomas, a 22-year old security guard, and his Portuguese-born girlfriend Claudia Patatas, a 38-year-old wedding photographer, were convicted in November by the Birmingham court jury. They were sentenced to six and a half years and five years of imprisonment, respectively.

They were both members of National Action, the first organization banned by the government in December 2016 under anti-terrorism legislation.

The couple wanted to restore the concentration camps. Pictures released at the trial included Adam Thomas holding his newborn baby while he was dressed in an outfit of the Ku Klux Klan (KKK), a white supremacist organization based in the southern United States. He had claimed that it was only a "game" while admitting to being racist and giving his son Adolf's middle name because of his "admiration" for Adolf Hitler.

The couple, who wanted to restore the concentration camps, had cushions decorated with swastikas at his home. The prosecution also produced messages and images broadcast by defendants on mobile applications, before and after the group's ban, demonstrating their attachment to National Action and Nazi ideology.

Adam Thomas was also found guilty of possessing, on his laptop, a manual containing instructions for making homemade bombs.

Four other members of the group sentenced. National Action was banned a few months after the assassination of Labor MP Jo Cox in June 2016, shortly before the Brexit referendum, by a neo-Nazi sympathizer. Four other National Action members were sentenced to up to six years and four months in prison for belonging to the neo-Nazi group.
