Greek Finance Minister Evangelos Venizelos said on Thursday Greece's participation in the euro could not depend on a referendum.

Greece's position within the euro area is a historic conquest of the country that cannot be put in doubt. This achievement by the Greek people cannot depend on a referendum, he said a statement.
