I’m assuming their AGM▸ has been cancelled?
I have been in touch with the secretary who tells me it has been cancelled. I'm also told that the branch had occasional telephone conference in the past (well before my time) but they made no binding decisions, and it sounds like that is not a route of choice due to limited success.
A booking for 4th June has been kept "in the hope that restrictions on meetings may be eased by then". I will post further news as I get it.
