Party expenditure and electoral prospects: a national level analysis of Britain

The effectiveness of campaign spending is a hotly contested issue. Much of that debate concentrates upon predetermined or assumed campaign periods. Yet, in a party and electoral system such as Britain, parties are continually campaigning. Party expenditure may therefore have a constant and cumulative effect. This article examines whether increased party spending at the national level is electorally significant. It analyses annual data from 1959 to 1994 and concludes that there is insufficient consistent evidence wholly to support this proposition.
