Pope Benedict in shock resignation

Pope Benedict XVI is to resign at the end of this month in an entirely unexpected development, saying he is too old continue at the age of 85. He became Pope in 2005 following John Paul II's death.

Resignations from the papacy are not unknown, but this is the first in the modern era, which has been marked by pontiffs dying while in office. At 78, the former Cardinal Joseph Ratzinger was one of the oldest new popes in history when elected.

He took the helm as one of the fiercest storms the Catholic Church has faced in decades - the scandal of child sex abuse by priests - was breaking. In a statement, he said: "After having repeatedly examined my conscience before God, I have come to the certainty that my strengths, due to an advanced age, are no longer suited to an adequate exercise of the Petrine ministry...

"In today's world, subject to so many rapid changes and shaken by questions of deep relevance for the life of faith, in order to govern the bark of Saint Peter and proclaim the Gospel, both strength of mind and body are necessary, strength which in the last few months, has deteriorated in me to the extent that I have had to recognise my incapacity to adequately fulfil the ministry entrusted to me."
