Sept. 18 (Bloomberg) -- Alitalia SpA's bidding group CAI dropped its offer for Italy's largest airline after failing to win the support of all nine labor unions for the government- backed rescue plan, news agency Radiocor reported.
The group, led by Piaggio & C. SpA Chairman Roberto Colaninno, withdrew its bid to buy assets from Rome-based Alitalia, the news agency said, citing people familiar with the situation.
