Party expenditure

Political parties would not need as many funds as they currently do, if certain political activites were disallowed.  I would therefore like to suggest we should ban all advertisements, be they on posters, lamp-posts or billboards, or be they in newspapers, magazines and/or other publications.  Other forms of political activity - canvassing, public meetings, rallies etc, along with the publication of leaflets,  policy documents, reports and books, as well as discussions and interviews on the media - would be allowed, as usual.  But posters and ads, (few of which say very much, anyway), would simply be banned.
