No offence to anyone, but to those who represent parties has anyone gone to the club or made direct contact (not via email) and requested a meeting with any of the board members face to face to ask this question? Like many organisations those in charge will focus on matters that they prioritise and in the case of the club, this is not the only business interest of some. Alternatively a formal letter requesting an AGM using the details outlined by various individuals citing the legal requirements sent to the club (director) in a signed-for and recorded capacity with a realistic deadline for response or engagement - after which actions can be taken. While contact via email is traceable its easily lost in the myriad of electronic communications and in many organisations (not saying this is the ICT case) its PA's or assistants who filter the mailbox of the senior positions, therefore act based on the priorities and instructions given.
I am in no way a defender of the club or the board as its clear they are avoiding their legal obligations and it can be reported to Companies House. Apologies if those from supporters groups or outspoken individuals have already exhausted avenues for contact, in which case escalation seems a practical option to force the issue. Otherwise there needs a united approach from all stakeholders to press harder in a manner that allows accountability.
