Forced to choose between Ms Marney, a 25-year-old former glamour model, and the party leadership, Mr Bolton announced that he had dumped his girlfriend.
He added that Mr Bolton would be "exceptionally foolish" to even remain a party member, and predicted a "swathe of members coming back to UKIP" as a result of his departure.
The NEC will shortly decide on an interim leader and "a leadership election will take place within 90 days".

He warned the party would now be unable to "capitalise" with Leave voters if Brexit is "further watered down or delayed".
It is estimated the party will have to stump up at least £200,000.
