LONDON (AP) — A convicted Mafia boss returned to his comfortable home in west London on Monday after a judge ruled that overcrowding in Italian prisons could violate his rights.

The decision, which Italy is likely to appeal, is a triumph for Domenico Rancadore, a 65-year-old who lived a quiet life under the name Mark Skinner for almost 20 years until he was arrested on a European warrant in August.
