Greece is now entering the heart of the country's problems and going through the "most difficult period politically," Prime Minister George Papandreou said during a cabinet meeting focusing on issues relating to the upcoming European Union summit on March 25 and government planning.

During the meeting held on Friday afternoon, he also appeared confident that Greece "will emerge from the tunnel".

"Our enemy in this effort are not just the various established interests but the mindsets that have been cultivated all these years," he said, identifying the problems as "inertia, immobility and force of habit".

He also announced that a detailed discussion within the party and the government on planning the next steps will be held after the end of the March 25 summit, which he said would mark "the end of the chapter now being written".

Also a part of this discussion would be the issue of exploiting the state's real assets in the best possible way, he added.
