The Times has a bit on the Westminster succession, it is obviously important for the Church in England and Wales. I have even had a couple of journalist ring up to ask my opinion, I am not sure what value that is.
The latest rumour is a Scot, the Bishop of Paisley, the Right Rev Philip Tartaglia, former Rector of the Scots College in Rome. We have a Scot as Prime Minister, the former PM was one, more heavily diguised, it is slightly less likely than Australian, though I wouldn't put money on it, a bit too much like colonisation.
The reference in the article to "international experience" is important; remember the Ratzinger/Kaspar debate over emphasis on the universal versus local Church before the Pope's election. Ratzinger seems to have won that one. The Pope seems to look for a sense of the Universal nature of the Church in future Cardinals. I think the reference in the last few paragraphs are worth taking seriously.
