Frustrated by the slow rate at which the results from last week’s local elections were reported, and the poor quality of the way in which these were displayed online, I set about creating an online, interactive map showing every borough and every ward in London, with the results for each candidate harvested from the borough websites.
Quite a lot of this was done using Claude Code and Cowork, which sped up the extraction of the candidate vote counts from each of the boroughs, each of which decided to publish their data in a slightly different way (or not at all, in the case of Newham and Brent, who waited until Monday before they released the data).
Utilising a set of ward boundaries from Ordnance Survey, the map includes each result from every ward, the results for the council in which they’re located, the strength of the vote for the winning party and ranking of all candidates according to the number of votes and share of the total.
You can view the map online here.
