LONDON (AP) — Cardinal Keith O’Brien had sparked more than his fair share of controversy before stepping down as archbishop of St. Andrews and Edinburgh on Monday and announcing he wouldn’t take part in the conclave to elect the next pope.

Known for his outspoken stances on abortion, same-sex marriage and flip-flopping on priestly celibacy, Britain’s most senior Roman Catholic leader raised eyebrows even before he was named cardinal in 2003.
