背景 前回の2024年総選挙で労働党は、1997年の総選挙以来となる地滑り的勝利を収めた。この選挙で単独で過半数に到達し、労働党は2010年に退任したゴードン・ブラウン以来14年ぶりの政権交代を果たした。

2024年7月5日、労働党党首キア・スターマーがバッキンガム宮殿を訪問しチャールズ国王に謁見、国王より組閣を要請され、正式に新首相に就任した。

下院議員の任期は5年のため、2024年に選出され、2024年7月9日に開催される予定の議会は遅くとも2029年7月9日までに解散され、次の総選挙がその後に実施されねばならない。

世論調査 イギリスでは、ウェストミンスター投票意向（Westminster voting intention）という形で政党の人気度を測っており、日本においては、政党支持率というより比例の投票意向調査に近い。 979x979px 調査範囲の表記 UK…イギリス全土 GB…ブリテン島のみ（北アイルランドなど除く） 2025
