This article forms part of a series, Radically rethinking our democracy, in which we asked contributors to propose bold answers to the question: how can we fix our democracy?
The problem is easy to state, but tricky to solve. Turnout in elections and referendums is often so low that the legitimacy of the result becomes open to question. When the United Kingdom voted three years ago to leave the European Union, Brexit was backed by 52% of those who voted – but just 37% of the total electorate. Should a major constitutional change be waved through without the explicit approval of almost two thirds of us?
Now consider the last general election to have produced a majority government. In 2015, David Cameron’s Conservatives secured an overall majority of 12 with the support of 37% of all voters – and just 25% of all electors. A combination of low turnout and our first-past-the-post system for electing MPs meant that three quarters of us were ruled by a party for which we had not voted.
The arguments about our voting system are discussed elsewhere in this series. So my concern here is the issue of turnout. How can we persuade more people to vote, and therefore to imbue the result of any electoral contest with greater legitimacy?
The most obvious answer is to make voting compulsory. Just as jury service is an obligation that we have as citizens if we are summoned to do it, so voting in elections and referendums could be considered a similar compulsion. This is the case in about 20 countries – the precise number depends upon how one classifies countries where compulsion in theory is seldom enforced in practice.
The case for compulsion is clear. It is not just that turnout would rise sharply, though it would. Going by the experiences of countries that have already introduced compulsory voting, it would rise from less than 70% in each of the last five UK general elections, up to something like 85-90%. (It is never 100 per cent: the electoral register is not perfect; electors die, fall ill, face family crises, are stranded away from home, or have some other legitimate reason for not voting; and some people are happy to risk the modest fine that might, or might not, be levied on non-voters.)
