Another interesting resignation: Cardinal O'Brien, the top-ranked Catholic in the UK, just resigned this morning after allegations of inappropriate behavior with younger priests, not boys, but still inappropriate.http://www.guardian.co.uk/world/2013/feb/25/cardinal-keith-obrien-resigns
Now he resigns and will miss the conclave. Something must be afoot.
Update: Turns out it appears that Ratzinger might have cut him loose rather than O'Brien resigning on his own:
"The Cardinal had already presented last November his resignation in view of his 75th birthday on 17 March 2013, and it was accepted by the Holy Father with the formula 'nunc pro tunc' (now for later). Given the imminent Vacant See, the Holy Father has now decided to accept the said resignation definitively."http://scmo.org/articles/-pope-accepts-cardinal-obriens-resignation.html
