"Greece asked for an extension of loans - it wants the money but does not want to commit itself to the set of obligations under which this money is given, which is not acceptable," Passos Coelho told parliament during a regular debate.

"Today it is quite clear that Greece will hardly avoid a third assistance package" given its aggravating financial situation, he added.

Passos Coelho said it was important for Europe to negotiate a solution for Greece "to build a new assistance framework, but this has to be done within the rules of the existing programme" and that Portugal's government hopes that Athens will regain its financial autonomy by completing its bailout programme like Portugal and Ireland did.
