James Whale has told UKIP general-secretary Jonathan Arnott that the party is "nutty" and rudderless without Nigel Farage.
UKIP will face its first real test under Paul Nuttall's leadership with the Copeland by-election. The consituency's former MP Jamie Reed, a vocal critic of Jeremy Corbyn, stepped down in order to take a job in the nuclear industry.
When Arnott, who is also an MEP, came onto talkRADIO to discuss UKIP's chances of winning the seat, James Whale asked him candidly about the party's future.
He told Arnott "there is no UKIP without Nigel Farage", and they're a bit "nutty" when they're not being led by him.
