Britain’s decision to leave the European Union is the most important event in the recent political history of the UK. However, days before election day, Labour’s campaign on Facebook seems to be ignoring the Brexit issue, an analysis by LSE researchers Damian Tambini, Nick Anstead and João Carlos Magalhães indicates. This post is the second in a series that is examining data collected as part of a joint project recently launched by the LSE Media Policy Project and the “Who Targets Me” initiative. In the first post, we considered the Liberal Democrat campaign. The project is studying political micro-targeting on the social media platform during the 2017 UK general election.
