That's remarkable Eric because I myself received a telephone call this week from an old friend asking me to exercise a proxy vote for him and his wife !
He explained that due to the short notice election they haven't got time to send out postal vote forms so they're advising people to use proxy votes. I hardly dare mention this because it seems so convenient to my argument , but they expressed a wish to do all they could to prevent Corbyn being elected - I certainly wouldn't have mentioned it but I had to when I read what you posted !
