Greek lawmakers are expected to approve an unpopular property tax as they battle to show they are serious about tackling the country`s debt crisis in order to receive a vital cash injection. ­Greek MPs are expected to vote on a property tax on Tuesday, and most analysts believe the law will pass due to the ruling party`s majority in the parliament. The property tax hike is part of the austerity measures put together to convince the EU and IMF to hand out an euro8 billion bailout loan. Meanwhile, Prime Minister George A. Papandreou is heading to Berlin to discuss the debt crisis on Tuesday evening. However, it is not known whether the euro8 billion cash injection, desperately needed by Greece, is on the EU leaders` agenda. Protesters are planning to gather outside parliament in an effort to prevent the new austerity measures being passed. The deep unpopularity of these cuts could make them very hard to deliver, as RT`s Sara Firth discovered. A series of austerity measures has hit the Greek people hard: they have endured cuts in government spending and suffered cuts to their pensions. A lot of people have lost their jobs and the unemployment rate is skyrocketing. And now many see this new property tax as the last straw. Publicly, EU leaders say a default by Greece is not an option. However, it appears that privately, they are looking at a controlled default as a very realistic plan B, Sara Firth said. And the people are really wondering whether their leaders have the political capabilities to defuse this crisis situation. George Katroungalos, a professor of constitutional law, believes a default is inevitable. The question is, who is going to control it? "Either we are going to have a default, a default that we can organize and protect our interests accordingly, or we are going to have a kind of controlled bankruptcy in a way that Brussels and the lenders are going to dictate to us," he said. Experts say EU leaders cannot afford to let Greece to leave the Eurozone, because if it can leave, then anyone can. A dangerous precedent would be set, opening an exit route for such countries as Spain and Italy, whose problems could result in the collapse of the entire monetary union. "The EU is trying to avoid a domino effect," says Katroungalos. "So practically they are trying to isolate us for us not to contaminate the rest of the Eurozone. Maybe we are going to be a useful sacrifice for them in order to show this kind of austerity measures are necessary - and if they are not followed by the letter, then the disaster is the only possible way out."
