Deputy leader Margot Parker and four of the party's spokesmen have stood down following Sunday's vote of no confidence in Mr Bolton by UKIP's ruling body.
Deputy leader Margot Parker, who is an East Midlands Member of the European Parliament, said Boltons "personal life took over the job he was elected to do" in reference to his former girlfriend Jo Marneys racist messages about Prince Harrys fiancee Meghan Markle.
Speaking to Premier on the latest chaos, the now independent, Arnott said it was far bigger than a leadership issue: "The problem can not be fixed, irrespective of Henry Bolton's leadership".
UK Independence Party leader Henry Bolton is ignoring calls for his resignation following his ex-girlfriend's explosive, racist messages about Meghan Markle.
"If the NEC decides to go down the road of months of further infighting and further negative media scrutiny by deciding to pass a vote of no confidence in me, I think that the reality is that the party is probably over", he said.
He said: "I respect the next steps in the constitutional process and will therefore not be resigning as Party leader".
But he insists Ukip cannot afford another leadership election and says the result of the no confidence vote will lead to fresh in-fighting that could finish off the party.

The committee does not have the power to remove him - that can only be done by a vote of the party's membership.
A defiant Bolton, who left his wife prior to his relationship with 25-year-old Marney became public, said: "I dont believe I have done anything wrong".

Instead, he has pledged to "drain the swamp" and reform the party's national executive committee (NEC), accusing them of putting a "distracting" leadership contest before Brexit-related campaigning.
Ukip's assistant deputy leader Mike Hookem joined the exodus saying he had lost the support of MEPs, party staff and grassroots members. "Now we have to have an EGM which is a cause of great concern".
