Reform UK, a political party led by pro-Brexit politician Nigel Farage, is challenging the political establishment in the UK with growing support (Independent, MSN [Daily Mail]). The question will be suspended on 14 August 2025 if still open and the outcome determined using data as reported by Politico's Poll of Polls (Politico, set date range to "6 MONTHS" and click "KALMAN" above the right side of the chart under the "United Kingdom — 2024 election results" graphics). Chart data will be accessed for resolution as soon as data through and including 14 August 2025 are first reported, if necessary. The percentage numbers displayed will control, irrespective of the line sequence on the chart. Whether elections are called early and/or take place during the question's open period is immaterial. If the Reform UK Party merges with another party, the polling for the merged party will count.
