It is the question of the moment in Europe: will the UK leave or remain in Europe? Less than 24 hours from the vote, here are eight things to know about the Brexit.
When it will happen.
The referendum will take place on Thursday 23 June 2016. However, this is not the first time the UK has had to decide on its position toward the EU: a similar referendum was held in 1975 and pro-Europe supporters won by far with almost 70% of votes.
Euro-skeptic argued that it has been more than 30 years since last time the UK population had a chance to have its say on the EU membership. They also maintain that the political and economic situation has radically changed during the last years and therefore what was true back in 1975 might not be valid anymore in 2016.
