(see related stories) Rome, May 6 - Italian Premier Enrico Letta said the Milan Expo, slated for 2015, is an opportunity for national growth and that a little 'visionary madness' is needed to make it - and Italian economic recovery - a success. "For the government (Expo) is a true and real priority," Letta told journalists in a press conference. Letta explained the food-themed Expo, called "Nourish the planet. Energy for life", will act as "a hub" for Italian economic recovery. "It is really represents the heart of the possibility for recovery," Letta said. Asked about criticism calling his political programme a book of dreams, Letta responded, "We need dreams. If we think of being here without having a little 'visionary madness' ... Even the Expo, seven years ago, was a visionary madness and here we are today. Dreams even serve the dry policy of numbers". "The Expo is ... a point of reference for the life of this government. From here we want to send a message of cohesion. We are a team, Team Italy," Letta added.
