Cardinal Keith O’Brien of Scotland resigned on Monday in the wake of explosive charges that he had made “inappropriate” sexual advances to four men, three of them priests, and one now a former seminarian, starting in the 1980s.

O’Brien said he would skip next month’s conclave to elect a successor to Pope Benedict XVI, leaving the United Kingdom without a cardinal’s voice in the election of a new pope.

In a statement, O’Brien said Benedict had accepted his resignation effective immediately, and he appeared to allude to the events surrounding his sudden exit.

“Looking back over my years of ministry: For any good I have been able to do, I thank God. For any failures, I apologize to all whom I have offended,” said the cardinal, who turns 75 next month, which is the mandatory retirement age for bishops. Cardinals retain the right to vote in a conclave until age 80.
