A study of by-election voting patterns predicts the Liberal Democrats could become the main opposition party...
A study of by-election voting patterns predicts the Liberal Democrats could become the main opposition party

Although the complex cycle of local elections can be a source of much confusion, there are occasions when it can be turned to advantage. Monitoring a party's progress or decline over not just one year but rather a series of years serves to operate as a belt-and-braces technique and strengthens any conclusions about the ebb and flow of popular support that we might wish to make.

The method works as follows. For each by-election, there is always a previous year when the ward was last contested at the annual May elections. By-elections held during 2002, therefore, will have an equivalent May election in at least one of the four years between 1999 and 2002. If a by-election occurs in a shire district with whole council elections, for example, that means that the point of comparison is 1999 when the seat was last fought. By contrast, a by-election in a metropolitan borough with annual elections could be compared either with the result in 2000 if the by-election took place before May or with that in 2002 if it was fought after May.

So far this year there have been 86 contests where each of the three major parties has fought both the

by-election and the relevant preceding May election

and where there have been no boundary changes in the intervening period. Of these, 40 were fought originally

in 1999, six in 2000, 15 in 2001 and 25 in 2002. Armed with this knowledge, we can calculate the average change for each party between this year's by-elections and each of the last four rounds of May elections.

The analysis is further strengthened if it can be related to the 'national equivalent vote' which then prevailed. This is an estimate of vote share for the three main parties had the elections been fought across the country as a whole. In May 2000, for example, the Conservatives were comfortably out in front with 38% of the national equivalent vote, with Labour on 30% and the Liberal Democrats on 26%. In 2002, by contrast, it is estimated that the Conservatives would have obtained 34%, only just ahead of Labour on 33% and with the Liberal Democrats back on 25%.

The final piece of the jigsaw involves taking the average change in each party's share of the vote and adding it to or subtracting it from that year's national equivalent vote.

What can this method tell us about the state of the three main parties, just six months away from the crucial test of the 2003 May elections?

For the Conservatives the news is, as anticipated, somewhat gloomy. During 2002 the party has failed to make significant by-election gains, even incurring some notable losses, as November's results confirm. The four comparisons show the party ranging between 32% and 34% of the national vote, fractionally better than in recent opinion polls but a long way short of resurrecting the party's chances of unseating Labour. The party is well down on the highs of 2000 (see table) but, more significantly, its support has hardly changed compared with 1999. Given that the majority of contests next year were previously fought then, the prospects of the Conservatives making dramatic gains do not look good.

Before the government becomes too excited by this news, however, it must acknowledge its own difficulties. While three of the four comparisons show Labour with between 31% and 33% of popular support, the fourth, comparing 2002 with 1999, suggests the party can count on attracting fewer than three in 10 voters. That appears to imply that by-election results in the shires - the location of most of the seats which have not been contested since 1999 - have been particularly poor for the party. Labour too must face next year's local elections with some trepidation.

Which leaves the Liberal Democrats. The party's by-election performance shows its vote share on the rise, whichever year provides the point of comparison. More significant still, the party's 2002 by-election share is on average four percentage points higher than in the same seats in 1999. Indeed, the party has gained more seats from Labour in the shires than have the Conservatives. If this pattern continues, then a poor Labour performance in 2003 is likely to mean good news for the Liberal Democrats, supporting the party's view that it, rather than the Conservatives, is now regarded as the alternative party of choice by many former Labour voters.

Nor should we forget the political fringe. Disillusionment with all the political parties is likely

to have played some part in the BNP's victory in Blackburn last month, and there is evidence of a growing willingness by voters to look outside the mainstream. In May 1999, 10% of votes were cast for independent and 'other' party candidates. It will be little surprise if that figure increases again.

Labour may excuse the loss of seats next year as natural for the party of government at the mid-term. It will be much more difficult for the Conservatives, however, if their progress remains sluggish. But that is precisely what by-election results are suggesting will happen. The circumstances look ripe for yet another crisis and inevitable demands for a change of leadership.
