A neo-Nazi who named his baby Adolf and swore to kill Jews is to be released from prison months ahead of schedule, according to the Portuguese daily Correio da Manhã.

Adam Thomas, from Banbury, Oxfordshire, was 22 when he was given a six-and-a-half-year jail sentence in Birmingham Crown Court in 2018 after being convicted of belonging to the proscribed neo-Nazi group National Action.

Thomas, who is reportedly a great-grandson of 1930s fascist Oswald Mosley, has also expressed intent to kill black people, convert Chinese people into biofuel and establish a branch of the Ku Klux Klan in Britain.

Thomas went on trial alongside his partner, Claudia Patatas, a Portuguese citizen and 16 years his senior, who was also convicted of belonging to the illegal group and handed a five-year jail sentence.

According to Spanish daily newspaper El Mundo, she was released early in 2019, just one year or so into her sentence.

Birmingham Crown Court heard that Patatas sent a WhatsApp message to convicted National Action member and “vehement racist” Darren Fletcher, declaring that "all Jews must be put to death".

Thomas was raised by his grandparents in Birmingham and at the age of 13 was placed in a Deliquency Prevention programme for his displaying racist behaviour at school.

In 2018, the JC revealed that Thomas once spent several months in Israel and had attempted to convert to Judaism, even attending a yeshiva in Jerusalem on a trial basis for less than two months, before being turned away.

After returning to the UK and working as a security guard at Amazon, Thomas met Patatas, a wedding photographer, who introduced him to far-right subculture.

After his release from prison, according to Correio da Manhã, Thomas must wear a GPS device, live in a pre-identified house and comply with a mandatory curfew.

The Parole Board said it did not know whether the deradicalisation programme Thomas allegedly underwent while in prison had been effective, according to the Portuguese paper.

A spokesperson for the Community Security Trust told the JC that the case “highlights the serious challenge posed by the release of extremists from prison when there is no guarantee that they have shed their dangerous views.

“It is vital that the relevant authorities keep a close eye on Thomas, and on any other similar extremists convicted of terrorism offences once they are released.”
