Slovakia has stalled in ratifying measures to revamp the eurozone's European Financial Stability Facility (EFSF) rescue fund, intensifying the threat of contagian within the continent.
Slovakia is the last of the eurozone's 17 members to vote on expanding the £440bn EFSF fund, which is aiming to stop a potential meltdown in Europe by rescuing Greece.
The country's coalition government failed to push through the measures by 21 votes, believing the volume of funding to bail-out Greece is too high.
The governing coalition had linked the vote to a confidence motion and as a result has effectively been toppled.
However, a second vote on the issue could be held soon and is expected to succeed, according to the BBC.
A number of the country's citizens believe Slovakia, the second poorest country in Europe, should not have to bail-out richer countries like Greece.
The moves to block the funding means Greece's next tranche of bail-out funding remains uncertain, with the next EU meeting taking place on October 23.
Ahead of the Slovakia vote, prime minister Iveta Radicova warned the country was prepared to block the proposals.
"What we are deciding on today is the good name of Slovakia, reliability, where it will belong... or if we exclude ourselves from the community of the successful," said Radicova.
