The new voting system for mayors and PCCs: how it affects democracy

This month’s elections for mayors and police and crime commissioners were contested under a revised voting system. In a post published yesterday, Alan Renwick found that this change had a substantial impact on the results, to the benefit of the Conservatives. Here, he concludes that it also harmed democracy. 

Elections of mayors and police and crime commissioners (PCCs) were previously held under the Supplementary Vote (SV) system, where each voter could express first and second preferences. Now they take place using First Past the Post (FPTP), where there is a vote for a single candidate. The previous post in this series showed that this change produced a marked shift in the outcome of the elections held earlier this month, and that it did so entirely to the benefit of the Conservatives.  

That a change in the rules should favour those in power who instigated it is already cause for concern: democracy requires a level playing field. But ministers might defend the reform on the basis that the new system is superior on democratic grounds to its predecessor and that it was introduced fairly. Both of these claims therefore require interrogation. How do the two systems compare in terms of democratic quality? And was the process through which the change in voting system came about appropriate?  

Which voting system is more democratic? 

As I outlined in a blogpost published when the bill changing the voting system was before parliament in 2021, ministers argued that FPTP is the more democratic system: SV, they said, allows losing candidates – those coming second in terms of first preferences – to win. But this argument is circular: it works only if we have already accepted the FPTP definitions of ‘winner’ and ‘loser’.

The new voting system for mayors and PCCs: how it changed the results

This month’s elections for mayors and police and crime commissioners were contested under a revised voting system. In the first of a two-part blogpost, Alan Renwick examines how the shift affected the results. He finds that the impact was substantial, and that it specifically benefited the Conservatives. 

The elections held earlier this month for mayors and police and crime commissioners (PCCs) took place under a revised voting system. The Elections Act 2022 abolished the previous Supplementary Vote (SV) system, under which voters could express first and second preferences, in favour of straightforward First Past the Post (FPTP). The changed rules were applied in four local mayoral elections last year. But this year’s local elections offered the new system its first large-scale outing: every part of England and Wales had either mayoral or PCC elections; a few had both. 

So how did the new system fare? Did it affect the results? If so, whom did it benefit? This post endeavours to answer these questions, while a second part, which will be published tomorrow, will examine how the change affected the democratic quality of the elections in the round. 

How the change affected the results 

Ten combined authority mayoral elections and 37 PCC elections took place on 2 May. Under the new FPTP rules, Labour won nine of the mayoral contests, while the Conservatives won one. In the PCC contests, the Conservatives won 19, Labour 17, and Plaid Cymru one.  

We cannot be sure what the results would have been had the former SV system still been in place, but we can make estimates grounded in evidence. To do so, it is easiest to break the contests down into three groups.

Reforming the mayoral voting system: do ministers’ arguments stack up?

This week, the Elections Bill was amended to replace the Supplementary Vote (SV) system used for electing mayors and police and crime commissioners (PCCs) in England and Wales with First Past the Post (FPTP). But, as Alan Renwick and Alejandro Castillo-Powell argue, the arguments put forth by ministers are not as convincing as they might at first appear.

Ministers plan to replace the Supplementary Vote (SV) system used for electing mayors and police and crime commissioners (PCCs) in England and Wales with First Past the Post (FPTP). The most detailed explanation for the change given so far appeared in a press release last month, which gave five arguments for the switch: (1) SV increases the number of spoilt ballots; (2) it allows ‘loser’ candidates to win; (3) FPTP improves accountability by ‘making it easier for voters to express a clear choice’; (4) FPTP ‘is the world’s most widely used electoral system’; and (5) SV is ‘an anomaly’ and ‘out of step with other elections in England’. In the written statement that first trailed the proposals, Home Secretary Priti Patel also said (6) that the change ‘reflects that transferable voting systems were rejected by the British people in the 2011 nationwide referendum’. Some of these arguments were repeated, though in less detail, when the matter was considered at the Committee Stage of the Commons bill’s scrutiny earlier this week.

This post assesses the government’s claims in turn. Some have merit, but important counterarguments are ignored. Voting systems should be treated with care: it is all too easy for those in power to manipulate them to their own advantage. Ministers have not adequately made the case that the change will be good for democracy.

1. Does Supplementary Vote lead to more spoilt ballots

Elections using SV in the UK typically see higher numbers of spoilt ballots than do those using FPTP. Electoral Commission data shows that 0.8% of ballots cast in local council elections in May – under FPTP – were rejected. That compares to over 2% in most elections under SV. In PCC elections, they stood at 2.9% this year, down from 3.4% in 2016. In London mayoral elections, they have ranged between 1.8% in 2012 and 4.3% this year. They have generally been around 2% in other combined authority mayoral elections, peaking at 2.2% in 2018.

That SV elections show higher rates of rejected ballots does not mean that SV itself is necessarily the culprit. The jump in such ballots in this year’s London mayoral election points to another factor: ballot paper design. The Electoral Commission notes the use in that contest of a new, untested design, split over two columns because of the large number of candidates, which voters described as ‘being confusing/complex’. Poor design similarly led to more spoilt ballots in the 2007 Scottish local and parliamentary elections. Another factor may be deliberate spoiling of ballot papers: the Electoral Commission noted anecdotal evidence of this in the 2012 PCC elections.

So SV elections do see more spoilt ballots than FPTP elections, but improved ballot paper design – and clearer guidance for voters – might ameliorate the problem.

The 2017 election manifestos and the constitution

Over the past two weeks the political parties have published their manifestos for the snap general election. In this post Chris Caden and Fionnuala Ní Mhuilleoir summarise the constitutional content, covering proposals relating to Brexit, the possibility of a constitutional convention, devolution, House of Lords reform, electoral reform, human rights and freedom of information.

Theresa May’s surprise election announcement left the political parties with the challenge of putting together manifestos in a matter of weeks. The Conservatives, Labour, the Liberal Democrats, the Green Party and Plaid Cymru all published their manifestos in the week beginning 15 May. UKIP followed on 25 May and the SNP on 30 May. With much of the election debate centring on whom the public trust to lead the country through the biggest constitutional upheaval in recent history, Brexit is unsurprisingly covered by all the parties. Attention on other constitutional issues has wavered somewhat as a result, but Labour and the Liberal Democrats both propose a constitutional convention to review aspects of the UK’s constitutional arrangements. The manifestos also lay out a variety of options in areas such as House of Lords reform, devolution, electoral reform and human rights.

Brexit

Negotiating Brexit is a major theme for all parties. The Conservative Brexit commitments include ending membership of the single market and customs union so that a greater distinction between ‘domestic and international affairs in matters of migration, national security and the economy’ can be made. This means negotiating a free trade and customs agreement between the UK and EU member states and securing new trade agreements with other countries. Theresa May’s party aims for a ‘deep and special partnership’ with member states. A successful Brexit deal would entail regaining control of borders, reducing and controlling net migration, but maintaining a ‘frictionless’ Common Travel Area for people, goods and services to pass between Northern Ireland and the Republic of Ireland. The manifesto controversially maintains that ‘no deal’ is better than a bad deal for the UK.

Labour also accepts the referendum result, but rejects ‘no deal’ as a feasible option and envisages something more akin to a ‘soft Brexit’. The party would scrap the Conservatives’ Brexit white paper and replace it with an agreement maintaining the benefits of the single market and customs union; the government’s proposed ‘Great Repeal Bill’ would be replaced with an EU Rights and Protections Bill to ensure no changes to workers’ and consumers’ rights, equality law or environmental protections. The party pledges to immediately guarantee existing rights for all EU nationals in the UK and UK citizens in EU countries, and would also seek to remain part of various research and educational projects such as Horizon 2020, Erasmus and the European Medicines Agency. Additionally, membership of organisations like Eurojust and Europol would be retained. Labour commits to no hard border between Northern Ireland and the Republic of Ireland.

Unlike the Conservatives and Labour, the Liberal Democrats and Greens pledge a second referendum after a Brexit agreement is concluded, which in each case would include an option on the ballot paper of staying in the EU. Preventing a hard Brexit is the first priority for the Lib Dems and as a result the party promises to fight for the continuation of UK membership of the single market and customs union. It also pledges to protect the rights of EU citizens living in the UK and UK citizens abroad, to maintain UK participation in the Erasmus+ programme and other EU-funded schemes, and to retain the European Health Insurance Card. The Greens set out a similar agenda.

The SNP wishes to mitigate what they see as the damage of Brexit with the proposal that Scotland should remain in the single market. The party seeks additional powers for the Scottish government including powers that will be repatriated from Brussels to the UK like agriculture, fisheries, environmental protection and employment law. Plaid Cymru, meanwhile, pledges to make sure ‘every penny’ of European funding for Wales is replaced by the UK government and that the Welsh share of the money promised by the Leave campaign (referring to the £350 million for the NHS) is delivered. It also demands that the UK government seeks the endorsement of each UK devolved legislature before any trade deal can be signed.

UKIP supports leaving the single market, the customs union and the European Court of Justice. The manifesto outlines that no ‘divorce’ bill should be paid to the EU and that Brexit negotiations will be complete by the end of 2019.
