UK Local Elections #2C – 2025 West England Mayoral Election – Review of My Forecast

May 6, 2025 By Nigel Marriott

Labour have retained the West of England Combined Authority (WECA) Mayoralty  As I predicted, the contest was won with less than a quarter of the vote and with a small majority (less than 3%).  Unfortunately, I had the Greens winning the mayoralty so on the face of it, this is a forecasting error for me.  However, when voters are as fragmented as they are today, measuring forecasting skill is not as straightforward as it might seem.

UK Local Elections #2B – 2025 West England Mayoral Election – My Final Forecast

April 27, 2025 By Nigel Marriott

The West England Combined Authority (WECA) Metro Mayor election of 2025 will probably be won with less than a quarter of all votes cast.  My analysis shows it is a 5-way marginal, the likes of which have never been seen before in England.  All five parties have reasons to be optimistic but as of now, I and most other forecasters make the Greens favourites to win the 2025 WECA mayoralty.  With an election this tight, the parties get-out-the-vote efforts will play a big part in the final outcome.

All forecasts, charts & tables are based on the latest polls as of 26th April 2025.

UK Local Elections #2A – 2025 West England Mayoral Election – My Initial Forecast

April 13, 2025 By Nigel Marriott

The West England Combined Authority (WECA) Metro Mayor election of 2025 will probably be won with less than a quarter of all votes cast.  My analysis shows it is a 5-way marginal, the likes of which have never been seen in England before.  Why no-one has polled WECA is a mystery because this is shaping up to be one of the most unpredictable elections I’ve ever seen.

My forecast puts the Greens first with 24% but it also puts Reform, Lib Dems & Labour just behind with each on 20% and the Conservative and Independent candidates bringing up the rear.  I am using a weighted average of four models of which 2 have Labour winning, 1 has the Greens winning and the 4th model (with the highest weight) has Reform winning.  That’s how unpredictable the election is and why we need a WECA specific opinion poll!

This article is based on polls as of 7th April 2025.  My updated forecast based on polls as of 26th April can be found here.

UK Local Elections #1 – My West England Metro Mayor 2021 Election Forecast

May 2, 2021 By Nigel Marriott

It will be close but I am predicting that the Conservatives will hold onto the West England Combined Authority Metropolitan Mayoralty on 6th May 2021.  By rights, they should not be winning but the 3 parties opposing them do not seem to understand the subtleties of the Supplementary Vote (SV) that is used in this election and they will end up splitting their votes to their detriment.
