Practice 1　　Some people call him “Guidone”—big Guido. Large in both physical stature and reputation, Guido Rossi, who took over as Telecom Italia's chairman on September 15th following the surprise resignation of Marco Tronchetti Provera, has stood out from the Italian business crowd for more than three decades. Mr. Rossi, who attended Harvard law school in the 1950s and wrote a book on American bankruptcy law, made his name as a corporate lawyer keen on market rules and their enforcement. He has since worked in both private and public sectors, including stints in the Italian Senate and as one of the European Commission's group of company-law experts. As well as running a busy legal practice, he also has a reputation as a corporate troubleshooter and all-round Mr Fix-It, and is often called upon to clean up organisations in crisis.　　His role at Telecom Italia marks a return to the company he headed for ten months in 1997, during its politically tricky and legally complex privatisation. Before that, Mr Rossi had been sent in to sort out Ferruzzi-Montedison, an agri-business and chemicals group, which had collapsed after magistrates uncovered tangentopoli (“bribesville”).
