As during the 2015 election, although less than then (−12.5%), most media coverage (32.9%) was given to the workings of the electoral process itself (e.g., electoral events, opinion polls, 'horse race' coverage, campaign mishaps). During the first two weeks of campaigning, members of the public, interviewed in vox pops, made up a fifth to almost a half of all sources in broadcast news. While in the first two weeks of the election period policy made up less than half of all broadcast coverage, over the whole campaign policy received more coverage in all media than during the previous election, particularly after manifestos were published in the third week, when close to eight in ten broadcast news items were primarily about policy issues. Policy around Brexit and the EU receiving most coverage overall (10.9%), and national events that happened during the campaign period (namely, the terrorist attacks on Manchester Arena and in the area of London Bridge), along with controversies over Trident, brought policy issues around defence and security to the fore (7.2%).
