Yesterday’s British election has produced a result the Tories have dreaded: a hung Parliament, or one in which no party commands a majority. Furthermore, the Tories have 307 seats, 19 short of a majority. To get to the 326 seats needed for a bare majority, they must cobble together a coalition consistent of no fewer than five separate parties, most of which are regional nationalists and left-wing, or turn to the major third party, the Liberal Democrats.
A coalition with Lib Dems is frought with peril for the Tories, for both policy and political reasons. Policy-wise, the Lib Dems are far to the left of the Tories on items like taxation, cutting spending, immigration, and defense. But the real deal breaker is widely considered to be the Lib Dems’ insistence on voting reform as a condition of entering into any coalition or alliance.
Britain’s two major parties, the Conservatives and Labour, have long benefited from the traditional “first past the post” (FPTP) electoral system. This system, identical to that employed in most states for American congressional races, breaks the electorate into single-member, geographically defined districts and then awards a district to the candidate who wins the most votes on election night, even if that person has well short of a majority. This rewards parties with geographically concentrated partisans and penalizes those with broad, but minority support throughout the nation.
The Lib Dems have been victimized by this system for more than 30 years. They regularly poll around a fifth of the vote but get at most a tenth of the seats. This happened again last night, as the Lib Dems received 23 percent of the votes, but only 57 of the 650 seats in the House of Commons.
The preferred Lib Dem solution is to adopt a “proportional representation” (PR) voting system. Much used throughout the world, this system in pure form eliminates districts in favor of one national electorate. Seats are awarded in proportion to the number of votes a party receives, with some minimum total set to weed out very minor parties. As applied to the British voting trends of the last 55 years, this would make the Lib Dems kingmakers in every Parliament, as neither Labour nor the Tories have received close to a majority of the total votes cast since 1959.
Applying a pure PR system to last night’s results starkly depicts the dilemma. Assuming a 5 percent floor, as is done in Germany, the Tories would have won 267 seats, or 40 fewer than they won last night. Labour would have won 215, 43 fewer, and the Lib Dems would have won 169, 112 more.
If a pure PR system were the only option available, it’s understandable why the Tories would avoid this like the plague. But there are many other voting systems used throughout the world that would hurt the Tories less while giving the Lib Dems added influence to reflect their voting strength. They could serve as the basis for a deal with the Lib Dems that can send David Cameron to 10 Downing Street while satisfying Lib Dem concerns.
The first is the single-transferable-vote system with multi-member districts that is used in Ireland. Under this system, districts elect between three and five members each, and each voter ranks the candidates in the order of their preference. Thus, a Tory voter might make the Tories their first choice, the Lib Dems their second choice, and so on. The votes are counted in rounds, with the low-ranking candidate eliminated in each round and his votes given to the candidate ranked in the next order of preference until a person gets a majority and is elected. The winning candidate’s votes are then reallocated to their voters’ second preferences until another candidate is elected, and so on until all the seats are filled.
This system gives minority parties representation in Parliament, but also gives majority parties a larger share of the seats than their share of the votes would afford them. In 2007, the leading Irish party, Fianna Fail, received 41.5 percent of the votes but 46.6 percent of the seats. This system also helps the Tories recapture some ultra-conservative voters who are currently casting ballots for the splinter UK Independence Party. UKIP received 3.4 percent of the vote last night; under the Irish system, those voters’ ballots would have been reallocated to the major party they supported next, presumably in most cases the Tories. The Irish system increases the Lib Dem influence while giving the Tories or Labour a chance to form a majority government with a plurality of the vote, just like now.
The second is a split FPTP/PR system like that used in Mexico. Under that system, half of the seats are elected just as they are now with a FPTP election, while the other half are awarded on a national basis according to PR. Applied to last night’s results, the Tories would have won 153 FPTP seats and 133 PR seats for a total of 286, only 21 fewer than they won last night. Labour would have won 25 fewer seats while the Lib Dems would have won 58 more. This system again preserves the ability of a party to win a majority of seats with a plurality of votes while giving the Lib Dems added influence.
A third approach is nearly identical to the Hungarian system, a split FPTP/PR system with the PR seats being awarded regionally. This gives the regionalist parties that have strength in Scotland, Wales, and Northern Ireland a chance to maintain or increase their influence as well. As applied to last night, and assuming England is treated as one region, the Tories would have won 280 seats, a 27-seat loss, but the Lib Dems would have only increased by 53, five fewer than under the Mexican-style system, with the regional parties increasing their share of the seats.
Note that under each approach, the basic fact of a Tory-Lib Dem alliance is unavoidable. That, however, is a result of the low Tory share of the vote, only 36 percent of the vote. Even under FPTP, it is very hard for the Tories to get a majority of the seats when they receive less than 40 percent of the vote. Any of these approaches would effectively raise the plurality share of the vote they would need to form a majority government but preserves the possibility of their doing so, unlike straight national PR.
If any of these systems are adopted, the Tories ought to insist on two other voting reforms that would directly benefit them and increase the fairness of the voting system. The first, fair apportionment, refers to how seats in the House of Commons are distributed among the United Kingdom’s four nations. Both Scotland and Wales are currently overrepresented when compared to their shares of the UK populations. Both Scotland and Wales are Labour bastions; Scotland in particular is a wasteland for the Tories, where they currently hold only one of the 59 seats. Fair apportionment would take 19 seats from these regions and add 18 seats to England (one would go to Northern Ireland). As the Tories carried England overwhelmingly, 40-28 over Labour, one should presume that most of these seats would be added to the Conservative column.
The final change is fair districting. In America, House seats must be drawn on the basis of one-person, one-vote so that the populations of each district are nearly identical to one another. In the United Kingdom, seats are drawn as much to keep certain communities whole as to equalize population. This has resulted in a systematic overpopulation of rural seats, which are overwhelmingly won by the Tories and the Lib Dems, and underpopulation of inner city seats, disproportionately Labour. Creating districts of more equal population will make the Tories and Lib Dems FPTP seat totals align more closely with the vote totals they receive.
The bottom line is that changes to the British voting system ought not to be a barrier to a Tory-Lib Dem pact. Tories have to give up some of the advantages of the current system, while Lib Dems have to give up the dream of being the permanent kingmakers in British politics. A compromise on this point could produce the stable and productive government British voters want and need.
