Should the United Kingdom adopt proportional representation?

The UK uses the first-past-the-post system for general elections to the House of Commons, where the candidate with the most votes in each constituency wins the seat. This often results in parties gaining disproportionate seats relative to their national vote share, as seen in recent elections where Labour secured a large majority with around 34% of the vote while Reform UK received over 14% but few seats. Campaigns like Make Votes Matter and Labour for PR push for proportional representation to better match seats to votes, amid shifting voter support away from the traditional two parties, though Reform UK recently withdrew its backing for the change.
