Eurozone: Risk of contagion seen from 'Greek disease' as EU ponders options
Analyst Simon Tilford, the chief economist at the Centre for European Reform in London, says its hard to gauge the overall impact of a default on debt by a eurozone member. "There is a risk at some point of Greece defaulting on its sovereign debt," Tilford says. "I think there is a very real risk of that. Then, it's very difficult, really, to say what would happen."
