Lawmakers' decision to push for a so-called "Grexit" came after the eurosceptic Finns Party, the second-largest in parliament, threatened to bring down the government if it backed another rescue deal for Greece, public broadcaster Yle reported yesterday citing sources close to the talks.
In Finland, it is the country's "Grand Committee" -- made up of 25 of parliament's 200 MPs -- which gives the government a mandate to negotiate on an aid agreement for Greece.
The Finnish parliament declined to comment on the media report.
Finnish Finance Minister Alexander Stubb, attending the Greek crisis talks in Brussels, meanwhile tweeted that he could not reveal the mandate given to him by the Grand Committee so long as the Eurogroup negotiations were still ongoing.

"The mandate is not public and the Finnish delegation will not discuss it publicly," Kaisa Amaral, the delegation's spokesman, said.
Finns Party leader Timo Soini, who is also the country's foreign minister, has repeatedly argued in favour a "Grexit", saying it would be better for Greece to leave the euro.
The aim of yesterday's Eurogroup meeting was for ministers to come up with a final verdict on leftist Greek Premier Alexis Tsipras's proposals for a third rescue package worth more than 80 billion euros (USD 89 billion), ahead of a make-or-break EU summit today.
Amid German warnings that the talks were "extremely difficult", a European source said the German finance ministry had drawn up an "internal paper" for Greece to leave the eurozone for five years if it failed to improve its bailout proposals. The paper was not distributed in Brussels, the source added.
