I'm somewhat entertained at the concept that a council would
A : be privy to secret information (I've often discovered they know nothing about big changes before the rest of us in 3rd sector knew)
B: Be competent enough to plan ahead quietly to allow for them (most spend I've dealt with professionally three months planning a meeting schedule and still can't make sure the room bookings match with the schedule)
And C: could keep it quiet without Marjorie from Accounts letting her mate Tony in the Libraries know about the meeting she just overheard.
I'm mildly reassured there is such faith left.
It's likely staffing (unsurprisingly people are hesitant to work in Social and events roles after last year) or any other number of planning issues..
A Conspiracy unless it's about the amount of cakes stocked in the Council office cafeteria is very unlikely.
