The man charged with shooting and stabbing to death a rising star of British politics gave his name Saturday as "death to traitors, freedom for Britain" during his first court appearance since the killing stunned this nation on Thursday.
Thomas Mair, 52, made the comment when a judge asked for his name in a London magistrate's court. Mair was officially charged Saturday with the murder of Jo Cox, a 41-year-old member of the center-left Labour Party who had been an outspoken advocate for refugees, immigrants and Britain's continued membership in the European Union.
Mair's statement adds considerable weight to the theory that Cox's killing was a politically motivated, far-right attack just a week before Britain is to vote on the highly contentious question of whether the country should stay in the E.U.
Although neighbors and family members have described Mair as apolitical, watchdog groups have unearthed evidence of decades-long affiliations with neo-Nazi and white supremacist organizations.
Prosecutors said Saturday that they had found extreme right-wing literature during a search of Mair's house, Britain's Guardian newspaper reported. They also said that Mair told police during his arrest, which came moments after the attack on Cox, that he was "a political activist."
