Furious fans stormed away from a Boomtown Rats gig after Bob Geldof insulted their clothes.

At the start of the show at the Brentwood Festival, multi-millionaire Geldof introduced the band by launching into a bizarre rant comparing the crowd's Primark clothes to his own bespoke outfit.

The frontman, who lives in a mansion in Faversham, said: "We are mega. And you are Brentwood. How do we know that you are Brentwood and we are mega?

"Because I am wearing a f*** off pretend snakeskin suit and [they] are wearing f*** off cowboy shirts even though they live in London.

Addressing a band member, he said: "This guy who you’ll remember as a slim handsome young lad is wearing a f*** off purple suit with an elasticated waistband so that when he gets even f****** fatter you won’t notice.

He continued: "On the other hand Brentwood, you are wearing wall to wall f*****g Primark."

Unsurprisingly the crowd was not very pleased with Sir Bob's sartorial slurs, and responded with boos and catcalls.

But Geldof ploughed on with his tirade: "What are you booing for? We’re in f****** Brexit land here guys. Yeah, we’re Irish, we’re still in Europe.

"It’s just as well we wrote that song because this year is about Theresa May. She’s gonna do you in.

"There’s always someone looking at you Brentwood."

Fewer people however were looking at the Boomtown Rats as insulted fans headed away from the stage, with many expressing their anger on social media.
