  1. Given that Sinn Féin MPs do not take their seats and the Speaker and deputies do not vote, the number of MPs needed for a majority is, in practice, slightly lower. Sinn Féin won 7 seats, meaning a practical majority requires at least 320 MPs.
  2. Nicola Sturgeon sat as an MSP in the Scottish Parliament for Glasgow Southside. Before the election, the SNP delegation to the House of Commons was led by Angus Robertson, MP for Moray, who lost his seat. Ian Blackford, MP for Ross, Skye and Lochaber, succeeded him.
