Members of Arthritis Care will debate calls to sack the charity's entire trustee board at an extraordinary general meeting today.
The meeting, prompted by a 5,000-strong member petition, will discuss a resolution demanding an end to contentious plans to reform the charity's branch structure and a motion of no confidence in the board.
The meeting comes despite the emergence of a compromise solution to the controversial reforms. A working group, comprising trustees and regional chairs of the charity, has recommended that branches that solely organise social events, which were threatened with expulsion from the charity under the original proposals, should remain within the fold. The new plan will go to the board for approval at the end of September.
But Celia Holmes, chair of the charity's South East England Region, said the olive branch was "too little, too late". She said: "The charity is in a poor financial state and rather than the reorganisation of branches it needs a proper business plan."
All members will be balloted by post on the resolution to sack the board, with the result announced on 17 September.
