True story ...
A friend meets a LibDem deliverer ...
Friend: Thanks for calling round but it's too late, I've done my postal vote.
LibDem: Lovely, thank you, may I ask if you supported us?
Friend: No, sorry, I voted for Antony Little
LibDem: But Antony Little isn't a candidate here - he stood in the General Election.
Friend: Oh. I have no idea who I voted for then.
UPDATE: for clarification this wasn't in Bowthorpe and the LibDem was right - I wasn't on the ballot paper!!
