Tony TraversThe Conservative and Labour parties have seen their combined share of the overall vote decline over the last several decades. This downward trend has been especially pronounced for Conservatives in Scotland and the urban North of England and Labour politicians in the South, making it harder for either party to win a general election outright. Unless the parties can solve the challenge of how to re-connect with their ex-voters and in places where decline has occurred, they will be consigned to become’major minority’ parties, writes Tony Travers.

The decline in Britain’s ‘two-party’ political system is well-documented. In the 1951 general election, the total Conservative-plus-Labour vote was 97 per cent, yet in 2010 it had declined to 65 per cent. The Liberal Democrats (and their predecessor parties, the Liberals and Social Democrats) had, until the 2010 election, been the main beneficiaries of this decline. Other parties, notably the Scottish National Party, Plaid Cymru, the Greens, Respect and the BNP have also played a role in reducing the dominance of Labour and the Conservatives. The chart below shows these changes.

As voter pluralism has increased, there have been differential impacts from one part of the country to another.  The Conservatives have seen their vote share decline significantly more than Labour in both Scotland and the urban North of England. Similarly, Labour has seen its vote share fall more than the Conservatives in the rural South. The next two charts compare vote shares between 1945 and 2010 in the North (North East & North West) and the South (South East, East & South West).

As a result of these voting changes, it has become harder for either the Conservatives or Labour to win a general election outright. The post-2010 Coalition was the result of the Conservatives’ failure to win a clear majority. Something similar may happen again in 2015, with either Labour or the Conservatives winning the largest number of seats, but possibly insufficient to form a majority government.

The decline of the Conservatives in the urban north and Scotland has coincided with the long period of de-industrialisation since the 1970s. As recently as 1978, the Tories were well represented on big city councils in the north of England. The table below shows the number of seats held by the major parties on four major northern city councils in 1978 and 2010 (both, within electoral cycles, relatively good years for the Conservatives).

The Liberal Democrats have been the main beneficiaries of the decline in Conservative fortunes in these major northern cities. They (and in some places others) have also supplanted Labour in a number of southern counties and districts. Again, both dates shown were reasonably good years for Labour.

As parties see their local government strength decline, there appears to be an impact on the capacity to win Parliamentary seats.  Two examples are given below, one affecting the Conservatives in Liverpool and the other Labour in Eastleigh. In each case, and even allowing for some modest boundary changes, Con-Lab contests have become either Lab-Lib Dem or Con-Lib Dem contests: one of the ‘major’ parties has slipped from being first or second in terms of votes to third or fourth. This pattern is repeated in a significant number of places. Council seats won by each party at the start and finish of the period are also shown.

There are substantial areas of the country where the major, traditional, parties’ vote share has declined precipitously since the 1970s. Unless the major parties can re-establish themselves in these places and with lost voters (in all areas) they are less and less likely to be able to win an election outright and could, potentially, be overhauled by an insurgent party.

During the Liberal Democrats’ period in government since 2010, their ‘protest’ vote status has been much reduced. This decline begs the question of where Liberal Democrat votes will go if the party’s share declines permanently to below its pre-2010 level. Looking ahead, it will be interesting to see whether UKIP can win (1) protest; (2) former Conservative and (3) ‘working class’ Labour votes.

For the Conservatives and Labour, there remains a key challenge: how to re-connect with their ex-voters and in places where decline has occurred. Alternatively, it is possible Labour and the Conservatives will continue to suffer attrition and face the prospect of simply becoming one of a larger number of ‘major minority’ parties.
