Former Ukip parliamentary candidate, John Rees-Evans, has become the latest person to announce a bid for the leadership of Ukip.
Mr Rees-Evans is best known for once accusing a "homosexual donkey" of trying to rape his horse.
Mr Rees-Evans apologised for his controversial comments made in 2014, describing them as "playful banter with a mischievous activist".
As he announced his candidacy for the leadership on the BBC, Mr Rees-Evans referred to the story: "I concede it was a mistake to be playful with an activist in the street, the fact is I'm not a politician.
"The guy was just asking me questions in the street.
"It was an error of judgment.
"I was very early coming into politics and I'm sorry if I offended anyone by doing that but can we please move on?"
The former Cardiff South and Penarth parliamentary candidate also admitted that he once took a handgun to Ikea in Bulgaria, where he has a home.
He said: "Yes, in fact I did because it simply wasn't safe to hand it over to the security and there were things I had to get."
Ukip has been plunged into turmoil since Diane James quit as leader after just 18 days in the job following the departure of Nigel Farage.
Mr Rees-Evans blamed Ukip's recent infighting on the fact it is a party of "freedom fighters without an enemy" after the Brexit vote.
Referencing his own experience in the British Army, Mr Rees-Evans said: "The Parachute Regiment, people are going out in the week, working hard, there are challenges.
"At the weekend with nothing much to do they end up fighting with each other - it's very common with fighters.
"Ukip is a party of fighters, what I'm proposing to do is direct all that aggression towards the enemy."
