The annual Eurovision Song Contest will hold its grand final on Saturday in Liverpool, with 37 countries competing for the pop crown. Six countries automatically qualify for the final, while the others must perform in the semi-finals. Viewers in participating nations can vote by phone, text message or app, and national juries of music industry professionals also allocate points to their favourite songs. The winner is decided by combining public and jury votes, with the combined “rest of the world” votes being given the weight of one individual country.
