Joseph Ratzinger has been elected as the successor to John Paul II in a fourth ballot by the 115 cardinals.

Confirmation of a newly elected pope came earlier as white smoke was seen from the Sistine Chapel chimney.

The election was also confirmed shortly after 1800 local time as the bells of St Peter's Basilica rang out.

Cardinal Ratzinger's appearance on the balcony of the Vatican, as the new pope, was met with rapturous cheers from the waiting crowds.
