The annual extravaganza began in 1956 and has always been a favourite with European television audiences.

For the first time, competitors from 43 countries will be singing their way through semi-finals on Tuesday and Thursday - with only 25 going through to the actual final on Saturday.  Ireland has been the most successful competitor, boasting seven wins. France has got five victories under its belt. But the French haven’t tasted Eurovision glory since the early nineties. So this year they’re trying something different.
