Feb 28 because he no longer has the strength to fulfill the duties of his office, becoming the first pontiff since the Middle Ages to take such a step.

The 85-year-old pope said he had noticed that his strength had deteriorated over recent months "to the extent that I have had to recognize my incapacity to adequately fulfill the ministry entrusted to me".

"For this reason, and well aware of the seriousness of this act, with full freedom I declare that I renounce the ministry of Bishop of Rome, Successor of Saint Peter," he said according to a statement from the Vatican.

A Vatican spokesman said the pontiff would step down from 1900 GMT on February 28, leaving the office vacant until a successor is chosen.
