I've had 4 lots and that's only because they came at a time when I was unusually at home. There may have been some while at work. The greens, labour, lib dems and Cons (but only for the council elections).
None, not for either Parliament or Council. There was only 1 chap handing out leaflets in Driffield last week on market day (apart from the usual Jehova's) and he was touting for UKIP. Seemed to be doing OK, but there was no other competition, as I've said.
