Reform UK leader Nigel Farage blamed Sir Keir Starmer after Britain’s youngest council leader was allegedly pushed in the street during a row.
George Finch, 19, claims a suspect branded him a “racist” and “fascist” while he was out early on Friday.
Farage told the Daily Mail: “I’m deeply upset that our young council leader was assaulted.
“The words used against him echo the Prime Minister’s disgraceful attack on Reform during Labour conference week and wholly irresponsible comments from the leader of the Green Party.”
Labour hit back saying it was “categorically incorrect” to suggest Sir Keir or the party had in any way been responsible for the incident now being investigated by police.
Finch, the teenage leader of Warwickshire County Council, claimed he and a female friend were “physically attacked” in Nuneaton town centre by a young man.
They were then followed, it is said.
The alleged attacker had been “wound up and sent into battle by the dangerous rhetoric of Labour and the Greens”, Finch alleged.
He said the incident didn’t cause any lasting injury but “came as a massive shock to me and my friend and was completely out of the blue”, adding: “I’m extremely concerned about the state of political discourse in Britain.
“Reform UK activists at all levels are suffering intimidation and violence at the hands of left-wing instigators.
“The politicians they follow know this, but are willingly allowing it to happen. They have a duty to speak out and quell the increased threat faced by my friends and colleagues.”
A bitter row broke out after the Prime Minister branded Reform's immigration policies 'racist' and claimed Mr Farage was an 'enemy' of Britain during his Labour Party conference speech in September.
On Monday, Reform’s head of policy Zia Yusuf posted on X, formerly Twitter: “The assailant shouted ‘fascist, racist’ - exactly the language used by the Prime Minister and the leader of the Green Party. They know exactly what they’re doing.”
Last month Farage said Sir Keir’s branding of Reform plans as racist “will incite and encourage the radical left” and “directly threatens the safety” of his campaigners as he accused the PM of descending “into the gutter”.
Sir Keir said anyone who argues that “people who have lived here for generations” should now be deported is “an enemy” of Britain.
Green Party leader, Zack Polanski, alleged Reform “fascists” plan “to deport our friends, our neighbours, our family members”.
A Labour spokesman told the Mail: “Violence, harassment or intimidation is completely unacceptable and has no place in our politics or our society.
“Any such incidents must be thoroughly investigated and the perpetrators must be brought to justice.”
Warwickshire Police said: “Officers are investigating an assault after we received a call at around 2am on Saturday, October 11, in which a man stated he had been pushed by another man in Nuneaton.
“Anyone who witnessed the incident is asked to call 101, giving incident number 26 of 11 October.”
A Green Party spokesman added: “There is no place for violence or intimidation in politics and using the disgraceful attack of a councillor to score cheap points is distasteful.
“The Green Party is committed to offering a message of hope to counter those looking to fuel division and hatred.
“And we will work to bring communities together and provide them with the investment they need to thrive.”
Labour were approached by the Standard for comment.
