THE GREEN BRIGADE have hit out at Sir Rod Stewart with an X-rated banner blast after the Celtic-daft rocker congratulated Boris Johnson on his general election victory.

The 74-year-old sparked a social media backlash on Friday when he praised the newly-elected Conservative Prime Minister just hours after the political triumph.

Thanking fans for getting his latest album You're In My Heart to number one in the UK, the crooner wrote: "Thank you once again to my legions of fans who I will never take for granted. Bless you all and a Merry Christmas.

"Well done Robbie, well done Boris, no hard feelings Pete Townshend!".

But the post clearly irked controversial Hoops fan group, the Green Brigade, who unleashed a stinging attack on the music legend during today's clash against Hibs at Parkhead.

The banner read: "Tories not welcome.

"F*** off Rod."

Supporters also chanted "if you hate the f*****g Tories clap your hands".

The explicit display was slammed by BBC pundit and ex-Hibs striker Tam McManus.

He wrote: "What even is this? Why not just go and support your team & watch a game of football?

"Cringeworthy attention seeking tripe."

Many Celtic supporters were left furious by the message, which was unveiled during the second-half.

One said: "Saw the GB banner at Celtic park today then checked a load of Celtic sites.

"To a man we are embarrassed by that banner. We know you’re a real Celtic man and we appreciate the support you show the club."

Another commented: "Rod Stewart supports Celtic. End of. His personal politics are nothing to do with anyone, especially not the wee boys in the GB with their stupid banners."

While a third added: "Fed up with all this Tory political nonsense. Wish the Celtic supporters would concentrate in supporting the team towards league and cups and the 10. Picking on Rod Stewart is a joke you should be ashamed."

But many others applauded the Green Brigade for the banner, which goes against the club’s ethos of being open to all since its formation in 1888.

One wrote: "Class from the GB today."

A second posted: "Loud and clear, f*** off Rod Stewart."

And another said: "Brilliant banner from GB today. Never liked that c*** Rod Stewart n the Tory's are scum."

Hours later, Rod's wife Penny Lancaster posted a Celtic tribute on Instagram.

She said: "So excited for the future of our BS ‘Hoops’ under 9’s team. Undefeated and Rod is so proud.

"Thanks for the extra star support of Gordon Strachan! 💚⚽️💚"

However, there's no love loss between Sir Rod and the Green Brigade after he blasted the ultras group for lighting flares in the club's win over Lazio in Rome.

The celebrity Hoops fan, who regularly follows the club at home and abroad, told The Scottish Sun: “We’ve got to be careful. We don’t help ourselves.”

The rock idol also told how he watched on in horror with Celts chief Peter Lawwell as some of the 9,000-strong travelling army lit flares inside the Stadio Olimpico.

The Sailing star said of the pyro display: “I looked along at Peter Lawwell and I said ‘We’re in trouble aren’t we?’ And he said ‘Yes we are’.”

It comes after Rangers claimed the singer was directed out of a plush Hampden lounge after hassling an Ibrox director's teenage son.

Sir Rod was at the national stadium last Sunday to watch Neil Lennon's side lift the Betfred Cup.

Former Scotland striker Alan Brazil sensationally claimed on talkSPORT that the son of a Gers official “went for Sir Rod” as his post-match celebrations spilled over.

But Gers chiefs furiously denied Brazil’s version of events and insist the youngster did not react and have demanded an on-air apology from the Celtic fan radio host for getting the story “spectacularly wrong”.
