A separate version of a bar chart showing the share of currently tabulated popular vote for each political party is available for each of the 650 constituencies. The party with the largest percentage of the vote counted is at the top and the least at the bottom.
There is a wider variety of parties shown on this chart because it is most granular. The chart only shows a maximum of 15 political parties. These bars will change over the course of election night as more votes are counted.
