Elections (Proportional Representation)

I beg to move,

That leave be given to bring in a Bill to introduce a system of proportional representation for parliamentary elections and for local government elections in England; and for connected purposes.

We are experiencing an unprecedented political moment in this country. Our most recent general election, in July this year, returned a Government with the second biggest majority of seats of any Government since the second world war, but on the lowest share of the vote ever recorded for a winning party. The first-past-the-post voting system used in UK parliamentary elections has delivered two thirds of the seats in the House of Commons to the Labour party, which attracted just one third of the votes cast. Thanks to first past the post, nearly 60% of people who voted in the general election in July are not represented in Parliament by the candidate that they voted for. This is the most disproportionate election result that this country has ever seen.

We are also seeing record levels of disillusionment with the political process, with citizens becoming increasingly disengaged. This is reflected in the fact that turnout in the 2024 general election was the second lowest since 1918, at just under 60%. Over 40% of registered voters in the UK thought so little of the political process that they did not think it worth expressing a preference for one candidate over another.

There are many urgent and pressing challenges facing the UK today, but it is essential that the vast majority of its citizens actively support the mechanisms by which the decisions are made to address them. Increasing levels of disengagement threaten our ability to respond both to immediate challenges and to longer-term issues.

The Liberal Democrats believe—and have always believed—that a fair voting system is an essential bedrock of a functioning democracy. Democracy has proved to be the most effective and enduring governing system because it relies on a broad base of support across the population. A faulty voting system delivering a majority Government on a minority vote undermines democracy and its ability to deliver effective government. That is why I am presenting this ten-minute rule Bill. In the face of growing worldwide threats to democratic Governments and institutions, the UK needs to urgently reassert the value of participative democracy as an essential component in peaceful and prosperous societies. To do that, we need to respond to the democratic challenges that have emerged in our own country by adopting the provisions in the Bill.

Will the hon. Member give way?

With pleasure.

Order. I remind hon. Members that interventions are not taken during the ten-minute rule speech.

Apologies, Madam Deputy Speaker.

The Bill would introduce a system of proportional representation for parliamentary elections and local government elections in England. Liberal Democrats have been calling for the introduction of a single transferable vote system whereby candidates on a ballot paper are ranked according to the voter’s preference. That system would protect the critical local link between MPs and their constituencies, which is valuable in connecting individual voters with the Parliament that makes decisions on their behalf. Constituency MPs understand the specific issues that voters in their seat are experiencing and can connect them to the broader issues facing the country. A system of STV would preserve that aspect of our current system, but would also ensure that MPs enjoyed the broad support of the majority of their electors.

In the most recent general election, the number of MPs elected to this Chamber with more than 50% of the votes cast in their constituency was just 96—a decrease from 421 in the 2019 election and 476 in the general election before that. Ten of our colleagues in this Parliament were elected with fewer than 30% of the vote of their constituents who turned out. Far fewer MPs today can say they have the support of the majority of their constituents, or even a broad base of support, than ever before.

Proportional electoral systems have been used successfully for elections in the UK’s devolved Parliaments and Assemblies since the turn of the century. One of the advantages of adopting STV for all local elections in England, as well as general elections, is that it is already in use in two of the four nations that make up the UK. Now Welsh councils also have the power to adopt STV if they wish, it may soon be three out of the four nations. Proportional representation through an STV system is not alien to the UK; millions of people across the country are already familiar with voting in that way. The use of proportional systems that retain a close constituency link across the UK makes Westminster’s use of first past the post the outlier rather than the norm.

I support continuing with the first-past-the-post system. When our constituents arrived at their polling station on 4 July, they knew what to expect: if their chosen candidate received more votes than any other, that is who would be elected as their MP. There is elegance to this simplicity. In our democracy, the person who wins the most votes in each of our 650 constituencies wins the seat. It cannot be denied that voters would be confronted with a far more complicated system if any type of proportional representation were to be introduced.

Crucially, after the election, every one of our constituents knew who to turn to if they wished to contact their Member of Parliament. For me, that is the most important feature of our democratic system. In a more proportional system, such as the single transferable vote system advocated by some across the House, constituencies would be represented by multiple Members of Parliament from various parties. Clearly, that would polarise our communities, and voters might contact only the MP they had voted for, which would absolve us of our duty to represent all our constituents. It would be far too difficult for voters to get to know the several politicians representing their area, and to hold them to account at the next general election. Constituents struggling with complex issues may already have exhausted other options. We do not want to make them ask which MP they should contact as well.

First past the post creates a strong connection, for good or bad, between residents and their representatives. Under our current system, I can represent my home of Broxbourne. Every one of my neighbours—whether they have an issue with their housing, their pension or anything else—knows who to turn to. There is a clear link that would simply be lost under a more proportional system. Having a sole representative for a small constituency allows each of us in this place to remain grounded, and ensures that every corner of our United Kingdom is properly represented.
