UKIP could be dead within months if the party's "existential crisis" isn't resolved, according to leadership challenger Paul Nuttall.
Nuttall, who is vying to succeed Diane James as UKIP's permanent leader, also told Julia Hartley-Brewer that he would provide a voice of common sense, while also suggesting the party should continue to be radical.
Appearing in the studio on Julia's mid-morning show, Nuttall said that if the current infighting is not sorted out "there is a chance that UKIP will not be here this time next time next year in the guise that it is now.
"I think that would be a disaster not just for the party, but for the country. If Ukip isn't an electoral force, the government may be able to backslide on Brexit."
UKIP was plunged into crisis when James quit as leader after just 18 days in charge, forcing Nigel Farage to return on an interim basis. The party received further unwelcome coverage when two of its MEPs - Mike Hookem and Steven Woolfe - became embroiled in a brawl at the European Parliament in Strasbourg.
Nuttall said UKIP now "needs a steady hand, someone who understands the party" and preached the message of "not evolution - evolution."
The Liverpudlian, who until recently served as UKIP's deputy leader, said the party should represent "simple, common sense. we say the things the people are saying in the street." However he also said "UKIP is at its best when its being radical."
