Celtic have released a strong-worded statement this evening amid growing concerns about fans' use of non-football-related banners at matches.
The club were yesterday punished by the SPFL for pyrotechnics, and today, in a separate matter, they have publicly condemned certain supporters.
Banners displayed at recent matches were criticised, as the club outlined their stance that they follow no political agenda.

A statement read: "Celtic Football Club shares the concerns communicated by our own supporters regarding the use of banners at recent matches.
"Celtic is an inclusive football club open to all, with no political agenda, as is clear from the Club’s Social Charter and Social Mission Statement, and no group of supporters, or any other organisation, speaks on behalf of Celtic.
"Everyone associated with Celtic recognises the important part that Celtic supporters play in inspiring the team and contributing to the Celtic spirit.
"Fan displays should support the team, or otherwise celebrate Celtic, and be consistent with the terms of the Celtic Social Charter, Social Mission Statement and other terms that apply to all supporters’ enjoyment of Celtic.
"That is why the Club developed a protocol regarding the use of banners and organised displays at Celtic Park, or any other stadia where Celtic plays, requiring the pre-approval of fan displays.
"Although there have been many occasions on which the Club’s protocol has been followed with great success and support for the team and for Celtic, unfortunately, there have been instances in the past weeks where the protocol has not been followed, with unauthorised banners, which had not been submitted for pre-approval in line with the protocol, displayed at Celtic Park.
"The Club is reviewing these events and relevant processes.
"We have enjoyed a good season so far, and we want to achieve, together with our supporters, as much as we possibly can as we approach the latter part of the season.
"We thank our fans for their continuing support and collective understanding that Club protocols, and safety and competition regulations, must be adhered to in order to protect the Club and our fans so that all Celtic supporters feel able to attend Celtic Park and all matches involving Celtic."
