Pope Benedict XVI to hold final papal audience in Vatican

Crowds have begun gathering in St Peter's Square in the Vatican for the Pope's final general audience before his resignation on Thursday.

Papal audiences are normally held inside a Vatican hall in the winter.
But such is the level of interest that the event is being held outdoors and 50,000 tickets have been requested. As many as 200,000 people may attend

The Pope, Benedict XVI 85, will be making one of his last public appearances - using his trademark white "popemobile" to greet pilgrims in St Peter's Square on Wednesday.
