Former British National Party leader Nick Griffin has been expelled from the party by its new chairman.
The party claimed he had harassed staff, made threats and brought the party into disrepute since being made honorary president in July.
Mr Griffin lost his seat as an MEP in May and had to make way for new leaders.
On Twitter he said he believed the party’s decision to terminate his membership had followed him telling a staff member he was a useless and lazy.
The party said it had formed a special conduct committee to investigate the claims against Mr Griffin. A statement said the party was “bigger than any individual”.
Mr Griffin’s historic views on the Holocaust were revealed in depth in May following the release of a series of previously secret documents.
They showed that, when questioned by police investigating race-hate allegations in the late 1990s, Mr Griffin suggested that the figure of six million Jews being killed in the Shoah was “utter nonsense”.
