As President Trump and Russian President Vladimir Putin make their way around Helsinki for Monday's summit, they will be met with some 300 billboards promoting press freedom. The ad campaign is run by Finland's largest newspaper, Helsingin Sanomat. Its aim, explained editor-in-chief Kaius Niemi, is to make a "statement on behalf of critical and high quality journalism." As we welcome the presidents to the summit in Helsinki, we @hsfi want to remind them of the importance of free press.
