ATHENS, June 1 (Xinhua) -- Greece strongly criticized on Friday a drachma contingency test carried out by Bloomberg which fuelled fears of a Greek default and a potential exit from the euro zone.

Bloomberg's customers briefly noticed on Friday a post-euro Greek drachma currency function shown up on their Bloomberg screens, sparking rumors internationally.

Bloomberg explained in a statement that it was nothing more than an internal function set up to test in the context of contingency planning exercises carried out in the normal course of business.

"Some rush to push Greece out of euro... due to amateurism or on purpose. Greece's currency is Greek people's choice, not markets'," Greek government spokesman Dimitris Tsiodras replied in a statement released to media.

"European counterparts in any opportunity repeat that they want to keep Greece in the euro zone. Many times we have witnessed contingency tests turning into exercises for speculators," the Greek official added in the statement.

The debt-laden country which relies on international bailout packages to stay afloat since 2010, is heading to national elections on June 17 for a second time in a month.
