I've got to go back to the polling station at my
previous address, as I haven't been sent a polling card to my
new address
Finally managed to get through to the Brum City Council "help line" and they said that just because I've registered with the council tax at my new address it doesn't transfer the new info across to the electoral roll.
So really no wonder some people can get away with rigging & having 9 or so postal votes sent to their addresses-BIG PHAT SHAM
