Even the Italian Federal Police Want to Participate in the Conclave

But even as preparations for the mass were being made, Cardinal Angelo Scola, the archbishop of Milan – and reportedly the hot favourite to be the next pope – suffered a blow.

Anti-mafia detectives swooped on homes, offices, clinics and hospitals in Lombardy, the region around Milan, and elsewhere. A statement said the dawn raids were part of an investigation into "corruption linked to tenders by, and supplies to, hospitals".

Healthcare in Lombardy is the principal responsibility of the regional administration, which for the past 18 years has been run by Roberto Formigoni, a childhood friend of Scola and the leading political representative of the Communion and Liberation fellowship. Until recently, Scola was seen as the conservative group's most distinguished ecclesiastical spokesman.
