I'm puzzled by the idea of a village hall not being big enough. Each person needs 4 square metres, or less if they are sitting with their back to a wall. I have a very small village hall, but it's still over 65 square metres, so we have a safe capacity of about 18 people, which is more than adequate for a PC meeting. If people choose not to attend, their absence should not be accepted. Can they honestly say they haven't been out of their homes for 14 months? No trip in the car, shopping, libraries, leisure centres, pubs, restaurants, visits to family and friends? If that's the case, are they able to represent their communities?
Outdoor meetings are a publicity stunt and unbecoming of a parish council.
