A former tax worker who described himself as "the ultimate genocidal racist monster" has been jailed for inciting hatred online after he was exposed by a BBC investigation.
Thomas Webster was sacked by HMRC and investigated by police after comments he made to an undercover journalist in the BBC programme 'Unmasked: Extreme Far Right'.
Webster, 29, from Lapworth, Warwickshire, admitted 10 counts of stirring up racial hatred online, including ones calling for the killing and extinction of his racial "enemies".
Webster also admitted to stirring up religious hatred and another count of stirring up hatred on the grounds of sexual orientation. He was sentenced to two years at Warwick Crown Court.

In his online posts, Webster said he wanted Jewish and gay people to be tortured and executed.
Webster also said he wanted to kill all Muslims until they were "globally extinct."
In one instance, he said if a migrant hotel was placed on his road he would "prepare for murder and prison time, I am serious".
Webster was a member of the far right group Patriotic Alternative when BBC Wales Investigates' undercover reporter secretly recorded him at two of the group's events in 2024.
He was filmed saying that in his job at HMRC he liked to "deliberately" give non-white people "bad information which sounds interesting, like I'm deliberately trying to sabotage them".
Webster was dismissed by HMRC in February 2025, a month after the programme was broadcast.

The HMRC said it took breaches of its standards "extremely seriously" and had "robust processes" in place to investigate concerns.
"Where standards are not met, we act decisively," HMRC said in a statement.
"Following an internal disciplinary process, the individual concerned was dismissed from HMRC and ceased to be employed by the department in February 2025."
Talking to the undercover BBC reporter, Webster self-identified as a "white totalitarianist" who believed in "a world where white becomes the default human race... all other races will be extinct".
Describing himself as "a guy who seeks trouble" while on a hike with other Patriotic Alternative members, he boasted that he would have "crushed [the] skulls" of a group of non-white men if they had walked near to him.
Following the BBC programme, police opened an investigation and linked Webster to several social media accounts, mainly on X.
He was arrested for inciting racial hatred in September 2025 and police used details on his phone and computer to confirm the accounts were his. He was charged in July and pleaded guilty last month.
A number of the offending posts were still visible on X in the weeks after Webster pleaded guilty, as well as dozens of others in which he used the most extreme racist language.
In these additional posts, which did not form part of the charges, Webster praised Adolf Hitler and the Nazis and told several prominent politicians that they should be killed or subjected to sexual violence.
In one of his X posts, Webster described himself as a "genocidal racist monster".
He described his wishes for people of several races to be killed and in one post said "the next Hitler will be a man like me!"
After BBC contacted X about the posts, they were taken down - but the company did not comment further.
Days before Webster's sentencing, BBC News found another active Substack account appearing to belong to him.
The account shared posts discussing Webster's arrest, as well as intimate details of his personal life.
It also included several comments about race, including one calling for the "total genetic extinction" of people from South Asia.
One comment claimed that these posts were made in spite of bail conditions heavily limiting Webster's internet use and explicitly preventing him from communicating via social media.
After the BBC contacted Substack about the content, most of the posts were taken down, although one for which Webster was charged is still visible. The company did not respond further.
