Polling stations across Greater Manchester opened at 07:00 BST on 18 June for a mayoral election triggered by Andy Burnham's resignation following his Makerfield by-election win and appointment as prime minister. More than 2 million voters are eligible to choose among seven candidates using the supplementary vote system, with results expected on Friday. A pre-appointment More in Common poll showed Labour's Bev Craig leading Reform UK's Sian Astley by 20 points.
