So, the bishopric of St. Paul's is pretty much smack in the centre my Middlesex. I had an antipope with whom I overthrown the former pope, thus installing him as the new pope. However, I overlooked that fact that he will take any land he has, with him. To the papacy. So the question is, how can I get St. Pauls back into British (Yes, the Empire of Britannia is alive and kicking) hands.
