Italy's economy minister said reforms and investments were the key to sustainable growth in all countries in Europe, as early vote counts suggested Greece had voted against austerity on Sunday in a referendum that could put it on a path to leaving the euro. "Reforms and investments are the key to get back to sustainable growth in all countries," Pier Carlo Padoan tweeted. In two other tweets, Padoan said shared rules across Europe could guarantee economic growth and employment, and that Italy would continue to work "for a strong and more integrated Europe".
