A row has erupted between Nigel Farage and Britain's biggest teaching union after it branded Reform UK a "racist and far-right" party.
National Education Union (NEU) members at their annual conference called for funds to be used to help campaign against Reform UK candidates.
The NEU's general secretary, Daniel Kebede, claimed there were "an awful lot of racists who are getting involved in Reform".
Farage reacted angrily to Mr Kebede's claims, accusing him of encouraging "indoctrination of teenagers in our schools" and vowing that his party would "go to war" with the teaching unions if it won the next general election.
The Reform UK leader campaigns for tougher action against illegal immigration and a "one in, one out" policy for legal migrants to ease pressure on housing and the NHS.
He has always insisted he is not a racist and has rejected calls from some Reform UK members to side with far-right activist Tommy Robinson.
The party has also stepped up vetting of candidates ahead of May's local elections in England after a series of racism scandals during last year's general election campaign.
