Proportional Representation: General Elections

Debate between Luke Akehurst and Florence Eshalomi

Thursday 30th January 2025 Commons Chamber

[Luke Akehurst]

I think that is a different subject to the one we are debating. If the hon. Gentleman does not mind, I will proceed on the subject of proportional representation.

We do not know how voters would behave if they were confronted with a different voting system. We cannot say that because Labour got 34% of the vote in 2024 under first past the post, it would therefore have got 34% if the 2024 election had been run under a proportional representation system. Voters change their behaviour to fit the voting system. There might also be new parties that would grow under a different voting system.

With tactical voting in its current form, we do not know how many Labour-identifying voters back other parties for tactical reasons in particular seats—the hon. Member for Chelmsford (Marie Goldman) mentioned voters who had spoken to her about doing so. We do not know how many supporters of other parties voted Labour for tactical reasons, or what the net impact of unwinding those factors might be on each party.

[Florence Eshalomi]

I thank my hon. Friend for his long campaign on this important issue. All of us have probably knocked on doors and spoken to voters who have said that they have never voted because their vote would not count. Does he believe that if we had a different voting system, people would be able to see that every single vote at the ballot box makes a big difference to who is elected on polling day? Does he share my concern on that?

[Luke Akehurst]

I do share my hon. Friend’s viewpoint, and I will come to that later in my remarks. We do not know how much turnout would increase in areas where it is now depressed because the outcome under first past the post appears to be a foregone conclusion. My hon. Friend anticipated the next thing I was going to say.

The current fracturing of the party system, with five parties getting more than 5% of the vote—the number is higher in Scotland and Wales—is probably here to stay. That means there are more marginal seats, more three or even four-cornered fights for marginal seats and more Members of Parliament elected on relatively low vote shares by historical standards. Ironically, that improves the range of viable choices for voters in many seats, and their chances of influencing the result in a meaningful way, because there are fewer safe seats. However, it is trying to pour a multi-party system into an electoral system designed for two parties, so it inevitably leads to more and more disproportional results, where the relationship between vote share and number of seats completely breaks down.

For instance, as has been mentioned, the Liberal Democrats got 72 MPs despite receiving more than half a million fewer votes than Reform, which got only five MPs. I do not blame the Liberal Democrats or my party for seeking to maximise seats rather than votes—that is the game we are supposed to be playing with our current system—but it is difficult to go out to the public and objectively defend such surreal disproportionality. It increases public cynicism about their ability to influence politics.

My motivation for supporting a move to a more proportional voting system is therefore not that I think it will provide an immediate or long-term advantage to the party that I have dedicated my life to campaigning for, and I hope that Members of other parties would not be motivated by assuming that proportional representation will accrue immediate narrow party advantage at Labour’s expense. On the contrary, as a social democrat, my approach to any critical question is based on the core principles of social justice, democracy and equality. That leads me to support a more proportional voting system, just as it leads me to egalitarian and redistributive answers to social and economic policy questions.

We should design an electoral system based not on whether it benefits us as individual politicians or our own parties at a specific moment, but on whether it delivers just and equitable outcomes that can logically be defended. In particular, we should apply the philosopher John Rawls’ theory of justice and try to measure the impact of each electoral system on the most under-represented party and the most under-represented voter, and argue for a system that treats parties and voters as fairly and equitably as possible and that gives voters as equal influence as possible over who represents them and who governs the country.
