Sir Elton John has said he's "ashamed" of the UK government for tearing people apart with Brexit, while performing in Verona, Italy as part of his ongoing Farewell Yellow Brick Road tour.
From his piano, the legendary songwriter told the audience that he is "sick to death of politicians, especially British politicians."
"I am sick to death of Brexit," he added. "I'm ashamed of my country for what it has done. It's torn people apart."
Before launching into a rendition of his 1995 hit Believe, the 72-year-old appeared to take a swipe at those who voted to leave the European Union.
"I am a European. I am not a stupid, colonial, imperialist English idiot," he raged, before lightening up the mood somewhat with a joke about shipping costs.
"I may have to pay f**king import duty on flowers I get flown over."
John was set to perform in Verona for a second time on Thursday 30 May, but was forced to cancel the gig after his vocal chords became inflamed due to a bad cold.
An events page on Facebook revealed the news, explaining: "He was struggling with his warm-ups before last night and it was touch-and-go if he would be able to complete the show.
"The cold conditions at the outdoor arena exacerbated the condition and unfortunately, after a night's work with a doctor today, his voice has gone. As such, it with a heavy heart that we have announce that tonight's show in Verona is cancelled."
