Greece is near bankruptcy and must give up part of its sovereignty to obtain the large debt forgiveness it needs to survive, a leading conservative member of German parliament was quoted as saying on Saturday.

Michael Fuchs, a deputy parliamentary floor leader for Chancellor Angela Merkel's Christian Democrats (CDU), also told newspaper "Real News" that the debt-laden country might be better off outside the eurozone.

"You are very close to bankruptcy," Real News quoted Fuchs as saying in an interview. "We can not agree to a 'haircut' without terms and conditions and therefore, Greece must give up something, like some of its national sovereignty -- at least temporarily," added Fuchs, who is also the chair of the influential CDU small business group in parliament.

"I am personally not absolutely convinced that this (eurozone membership) is the best long-term solution for Greece to become quickly competitive," he added.

EU leaders will meet in Brussels on October 17-18 to discuss revising a July 21 deal to provide the country with a second rescue package. They may ask investors to accept losses on their holdings of Greek debt even larger than the 21 percent write-down set out in the July deal.

Fuchs had said on Monday that Greece may require a haircut of at least 50 percent.
