Leaflet tactics - are Labour smarter than the rest?

A slightly arcane but, I think, interesting topic this one. Section 91 of the 1983 Representation of the People's Act basically entitles election candidates to each have one piece of election literature delivered by the Royal Mail for free.

In York Central the Conservatives and the Lib Dems both appear to have done the same thing, that is to use their free mailshot to have one leaflet delivered to everyone on the electoral register. So far so straight forward.

The problem arises when you have houses where more than one person is on the electoral register, for instance there are three people registered at my address. The result is that three identical leaflets from the Conservatives turned up at my house on the same day, and then a week later three identical leaflets from the Lib Dems turned up. One of these leaflets get read and the other two get discarded.

What Labour appear to be doing is breaking their mailshot down into stages. So last week we received one leaflet addressed to one of the people at my address. This week we received a different leaflet addressed to another one of the people at my address, and one presumes we will receive a third leaflet to the third person next week.

The impact is that Labour effectively get double or triple value from their free Royal Mail delivery. At the same time they lessen their reliance on local volunteers pounding the streets doing deliveries and potentially make their campaign seem more active than it really is.
