Rome, August 5 - A leading tourism operator said on Monday that finance police crackdowns on tax evaders at posh resorts was bad for business. Finance authorities launched a weekend blitz in the Costa Smeralda area on Sardinia, looking for luxury boats and other symbols of wealth that might not have been properly declared on Italian tax returns. Flavio Briatore, entrepreneur and jet-setter, dismissed the raids saying authorities have already driven away the wealthiest tourists from the region. "Let them do all the checks they want, there is not much here," he said, adding that the largest spenders have fled. "The wealthiest, those with the biggest yachts, have already gone". Tourism is suffering in Italy as the country endures its deepest recession in more than 20 years.
