Estonia's hopes of becoming the 17th member of the Eurozone were hanging in the balance today after European Union commissioner Olli Rehn was quoted by dpa as saying the Baltic state's membership was "not a done deal.", according to dpa. Speaking in Brussels, Rehn's words, quoted by Dow Jones, were quickly picked up by local Estonian media and regional analysts including Danske Bank's Lars Christensen. Christensen said the worsening of the situation in Greece and the risk of contagion to other risky markets have raised the question of whether the Eurozone is ready to grow beyond its current 16 members. "In particular, some members are acting in ways that the core-EU countries, such as Germany, consider to be extremely irresponsible," Christensen said. -- SPA
