Nigel Farage has given short shrift to the Prince. "I'm not intending to accept the offer," the Ukip leader said, joking: "I've been trying to keep violence out of the election."
Prince Zylinski's family was just one of the many royal families chased out of Poland during the second World War and have bebuild their palace and resided in West London ever since.
The title holds no power in Poland but the Prince was the heir to the hereditary aristocratic title.
"Enough is enough, Mr Farage.
"So what I'd like to do, Mr Farage, is to challenge you to a duel.
"I'm offering a duel, if you agree.
"I would like us to meet in Hyde Park one morning with our swords and resolve this matter in a way that an 18th century Polish aristocrat and an English gentleman would traditionally do.
"Are you up for it, Mr Farage?"
Mr Zylinski acknowledged that getting Mr Farage to agree to a sword duel may be unlikely and so also offered a TV debate before the General Election.
He said: "Alternatively, if you don't agree, or if your sword is a little bit rusting, Mr Farage, we can meet for a different kind of duel - a duel of words in a TV studio in the run-up to the election.
"I'm up for it, it would be really nice - hopefully you will agree." - The Telegraph
