The Green Brigade have launched a new campaign urging Celtic fans to "agitate for change".
The influential ultras group unveiled "Celtic Shared" on Tuesday night, a campaign aimed at eventually placing the club under fan ownership.
Green Brigade protests have led calls for major overhaul in the boardroom and dugout this season as the club's 10 In A Row campaign hit the skids.
A statement insisted the initiative aims to "unite" supporters under a common goal of changing how Celtic is run.
It read: "Celtic Shared is a campaign, co-ordinated by the Green Brigade, which aims to unite as many Celtic supporters, supporter's clubs and organisations as possible, to agitate for change in how our club is run, to pave the way for genuine greater fan engagement and to promote the principle of eventual fan ownership of the club.
"We believe that fans are the lifeblood of the club and must unite to ensure our voices are heard."
The campaign's launch was accompanied by a YouTube video quoting manager Neil Lennon and recapping some of the major events of the season.
That included angry protests outside Celtic Park and Monday's statement from chairman Ian Bankier on the now infamous January review.
