neo-Nazi

The inquest, held over four weeks in February and March, heard Rhianan had been groomed and sexually exploited online by an American neo-Nazi, and that she had become "fixated" on Adolf Hitler and wanted to "blow up a synagogue".

The watchdog charged with holding MI5 to account rewrote a report into the handling of a violent neo-Nazi agent after the Security Service gave it false information, the BBC can reveal.

MI5 lied "deliberately and repeatedly" as it tried to defend its handling of a neo-Nazi agent who abused women, the BBC has told a panel of High Court judges.

The case, which began in 2022 with an attempt to block the BBC from publishing a story about the neo-Nazi agent, has become a major test of how the courts view MI5 and the credibility of its evidence.

An MI5 officer had confirmed the agent's status as he tried to persuade me to drop an investigation into X, a violent neo-Nazi misogynist who used his Security Service role to coerce and terrify his former girlfriend, known publicly as "Beth".
