[European Commissioner for Economic and Financial Affairs Pierre Moscovici attends a news conference with Portugal's Finance minister Mario Centeno in Lisbon]The European Union should discuss debt relief for Greece and potentially move ahead even without the International Monetary Fund, Portuguese Finance Minister Mario Centeno said in an interview published Tuesday by the Bild newspaper. Euro zone finance ministers are due to discuss wide-ranging debt relief for Greece when they meet next month, but German Finance Minister Wolfgang Schaeuble has opposed such measures, saying it would weaken efforts to enact further reforms. Centeno said the EU could proceed with debt relief for Greece, even the IMF does not participate.
