Nigel Farage allegedly walked away from a crash involving his chauffeur-driven 4x4 and a car carrying a dad and a toddler son.
Pub landlord Patrick Tranter, 38, says he was involved in the smash in Titsey, Surrey, at 9.30am on Thursday.
Patrick claims the former UKIP leader failed to check on him and his 13-month-old son, George, who was left crying in the backseat.
Farage, 55, insisted he checked to see if the pair were unharmed but claimed Patrick was abusive.

Patrick said he and his son had to go to hospital following the crash and claims his Jaguar Series 3 vehicle was written off after the collision.
“We crashed with an enormous bang," he told the Sun.
"Farage could not possibly have failed to hear George screaming. I ran out to see if my little boy was OK.
“Farage stepped out of the Range Rover, collected his bag from the boot and walked off.
“He didn’t have the common decency to see if we were OK, and never even looked back."
He says he has now banned the politician from his George and Dragon pub in Westerham, Kent, as a result.
Patrick said: “He lives two miles away and loves a pint, but he won’t get one from me. Man of the people, my arse. As far as I’m concerned he’s barred.”
The Brexit Party leader appeared on BBC Question Time later that evening where he debated Anna Soubry ahead of the European elections.
Nigel Farage, who admitted that he has visited the pub once previously, said: “If I’m banned, then it’s not too terrible is it?”
