The grand final of the Eurovision Song Contest takes place in Moscow later, with 25 countries aiming for glory.

The UK will be represented by Jade Ewen, who is singing Andrew Lloyd Webber's song It's My Time.

Norway's singer and violinist Alexander Rybak is the bookmakers' favourite to win, closely followed by Greece, Turkey, Azerbaijan and the UK.

Graham Norton will make his debut as commentator for the BBC, replacing Sir Terry Wogan, who bowed out last year.
