Reform UK is the most popular party in the country. However, if they do not get 50% of the vote, they cannot form a government. As of June 2026, they have around 25%, so they would have to form a coalition. Currently, their only viable option for this would be the Conservatives. While it is unlikely that all Conservative seats would join Reform, this site tracks the polls, and if the Reform and Conservative votes make up at least 50% of the vote, it shows that Reform could form a coalition with the Conservatives. If Reform or Labour get 50% in the polls, the site will update, and if Labour, Green and the Lib Dems can form a coalition, it will show here too.
