I have to agree with Antiochian. When I sent my resignation to my local party (not over Brexit) I received no acknowledgement and I am still being bombarded with material (email and post) from both local and national parties.
I can assure anyone concerned that lapsed/ resigned members are NOT included in the membership total.
And that - in our case at least - claims of a record membership are correct.
