Some councils are continuing to meet via zoom as 'informal meetings' and have a scheme of delegation for the clerk to make decisions following these meetings. It is not ideal and in a grey area but some councils are faced with very small halls and / or vulnerable councillors and so have made this decision.
There is a government consultation taking place at the moment on the subject of virtual meetings and so we might find there is a legislative change at some point based on the outcome of this consultation.
