A Remembrance Sunday tribute ruined in nine seconds, but it is a subsequent wall of silence from Celtic that most perturbs the rest of Scottish football.

Green Brigade boos, offensive banners and pro-IRA chants were as grimly predictable as the three points that followed for the in-form Scottish Premiership champions on Sunday.

Post-match frustrations vented by Kilmarnock manager Derek McInnes, however, betray a growing sense within the game that Celtic – and, in turn, its far-left ultra followers – are becoming unaccountable.

“I don’t get any decisions,” McInnes said in response to the “awful” show of disrespect, before adding Celtic “even decided when the minute silence stops”. “I’m not a politician or anything, but it’s our ground, it’s our minute silence,” he added.

Celtic’s Green Brigade group of radical anti-establishment campaigners have dialled up their incendiary gestures year-on-year since the group was formed in 2006. After the death of Queen Elizabeth II, pre-match commemorations were met with the banner: “If you hate the royal family clap your hands.” The group also held up pro-Palestine messages immediately after the Hamas terror attack in Israel on October 7 last year.
