Nigel Farage has denied knowing anything about his party's 2010 manifesto - despite the fact he campaigned for it.
On BBC's Daily Politics, presenter Andrew Neil asked Farage: "Ukip is now against replacing Trident?"
Farage responded that the debate had been "kicking around for some time" before adding that he had "no idea" where Neil had got the information.
The interviewer promptly informed Farage that the information came from Ukip's own website.
Farage was also asked whether it was still party policy to introduce a compulsory dress code for taxi drivers and for trains to be repainted in national colours.
In the party's election pitch, it was suggested that the London Underground Circle line should actually run in a circle.
He was challenged on the programme by Louise Cooper, a financial analyst over suggestions he had made that women with children were "worth less" to employers than men.
Cooper said that his belief that there was "no discrimination" against women was "laughable".
She said: "I try hard not to lose my temper on air and I try hard not to insult people on air; for you I'm going to make an exception. What you are saying is laughable - you are talking out of your bottom."
Cooper added: "For all the working mothers out there who are battling day to day, who are discriminated against, who are paid less than their male colleagues, who are looked over for promotion, I say shame on you, and I say double shame on you because you actually have daughters.
"What sort of example are you setting to your daughters?"
