The Brexit Party leader did not hold back when he launched a tirade of abuse against Meghan Markle and Prince Harry, the Duke and Duchess of Sussex, deriding them as “irrelevant”.
But royal fans have been left open-mouthed after Farage turned his attention to Prince Charles.
He ridiculed him for his environmental campaigns and said he hoped the Queen would reign for a “very, very long time” so as not to be replaced by her oldest son.
Mr Farage heaped praised on the Queen, describing her as an “amazing, awe-inspiring woman we’re bloody lucky to have her”.
But he didn’t pull any punches when it came to her son – and heir to the throne.
The Guardian reports that during the extraordinary attack in a fiery speech at Sydney’s Conservative Political Action Conference, he said: “When it comes to her son, when it comes to Charlie Boy and climate change, oh dear, oh dear, oh dear.”
He then turned his attention to the late Queen Mother, adding: “Her mother, Her Royal Highness the Queen’s mother was a slightly overweight, chain-smoking gin drinker who lived to 101 years old.
“All I can say is Charlie Boy is now in his 70s … may the Queen live a very, very long time.”
He went on: “Well, if I want the Queen to live a long time to stop Charlie Boy becoming king, I want Charlie Boy to live even longer and William to live forever to stop Harry becoming king.”
Farage said he hoped Prince William lived for longer to stop his younger brother, Prince Harry, ever becoming king.
This is despite Prince Harry being sixth in line to the British throne, behind Prince William’s three children, Prince George, Princess Charlotte and Prince Louis.
This is not the first time the former Ukip leader has attacked Prince Charles.
In 2008 he criticised the future king’s advisers as “naive and foolish at best” after Prince Charles delivered a speech on climate change.
Harry and Meghan Markle weren’t excluded from Farage’s onslaught either, The Guardian reports.
He reportedly said: “Terrifying. Here was Harry, here he was this young, brave, boisterous, all male, getting into trouble, turning up at stag parties inappropriately dressed, drinking too much and causing all sorts of mayhem.
“And then, a brave British officer who did his bit in Afghanistan. He was the most popular royal of a younger generation that we’ve seen for 100 years.
“And then he met Meghan Markle, and it’s fallen off a cliff.”
Prince Harry, earlier this month, revealed his plans to have “two kids, maximum” with his wife Meghan in a bid to help save the planet.
But Mr Farage blasted the decision, saying Prince Harry became the “prince of wokeness” when he married Meghan, according to Australian media reports.
