Treasurer Barry Gravenell told the BBC: “All the officers felt they could no longer support Reform UK after the way Rupert has been treated.
“We want to show Rupert that he has our full support.
“There are no plans for the future of the Great Yarmouth Reform party, the officers have all resigned we are now normal members of the public.”
The former Southampton FC chairman is currently under investigation by the party and the police over claims he made verbal threats of violence towards Reform chairman Zia Yusef, and allegations of bullying made by former staff members at his parliamentary and constituency offices.
Mr Lowe has strenuously denied the allegations and has threatened Reform with legal action.
In response to the Yarmouth Reform branch closing, Mr Lowe said: “These are good people who have shown huge courage.
“I sincerely appreciate their support.”
A spokesman for Reform UK said: “We have 450 branches – so that’s 0.2% of our total branches.
“During the last eight months, Reform has delivered the greatest political acceleration in British history. We have added 160,000 new members and opened 400 branches.”
