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’.
