Evangelos Venizelos, the head of Greece\'s Socialist party, said European politicians arguing for Greece to leave the euro zone are attempting to \'castrate\' the currency bloc, dpa quoted his party as announcing Tuesday. \'Some who think it right to exert pressure on Greece by teaching it a lesson need to know that they are emasculating the eurozone with these tricks,\' Venizelos said in a speech to parliamentarians Monday night. Last week, Greek Prime Minister Antonis Samaras held a series of top-level meetings in Berlin and Paris following signs of growing political tensions, especially in Germany, over aid to Greece. \'Our European partners and our German friends have given us no money and have lost no money. The only way (possible) to lose money is after an exit of Greece from the euro,\' Venizelos said. The Greek Socialists, along with the Democratic Left Party, support the coalition government led by the Samaras and his New Democracy party.
