Pope Benedict XVI is to resign at the end of this month in an unexpected development, saying he is too old to continue at the age of 85.

In a statement, the pontiff 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."
