The Cannes Festival draws to a close on Saturday, with a wry Iranian film about political prisoners and a Ukrainian-directed drama about despotism among the frontrunners to pick up the Palme d'Or top prize.
After almost a fortnight of glamorous red carpets and some politics, French actor Juliette Binoche and her jury will announce the winner from the 22 films vying for one of the world's most prestigious cinema awards.
