BRATISLAVA/PRAGUE, Nov 24 (Reuters) - There is a very real risk that the euro zone may break up or cease to function properly under the weight of the debt crisis gnawing away at its periphery, Slovakia's finance minister said on Wednesday.
Ivan Miklos spoke as policymakers in the currency area discussed billions of euros of aid for debt-laden Ireland, workers went on strike against austerity measures in Portugal and politicians bickered over rules for smoother crisis response in the future.
His comments mirrored a statement by German Chancellor Angela Merkel who said on Tuesday that the euro was in an "exceptionally serious" situation.
Miklos, a fiscal hawk in the centre-right Slovak cabinet, spoke about the euro zone problems in the context of Estonia joining the single currency in January.
"Even in the current conditions, which are very tough, very complicated and when the risk of a euro zone break-up, or at least its very problematic functioning, is very real, despite all that, Estonia will become a new member in January," he said in a debate at a university in Prague.
He added that euro zone membership was still favourable for Slovakia, boosting its economic growth by about 1 percentage point, but if Bratislava were to have to make the decision about joining now, it would be a much tougher call.
Slovakia has been an outlier in the euro zone. It joined the the single currency last year as its poorest member, but instead of the desired safe haven after years of fiscal reforms it was asked to cough up cash to rescue much richer Greece, which got into trouble against a backdrop of fiscal profligacy and accounting tricks.
Slovakia angered its euro zone partners by refusing to take part in the Greek bailout, but it agreed to provide aid to Ireland via the European Financial Stability Facility (EFSF), since Dublin's troubles were caused the banking sector rather than government spending. [

CLEAR RULES NEEDED TO PREVENT CONTAGION
Miklos rejected suggestions made by some EU member politicians that Ireland should raise its low taxes as part of any rescue deal and said he explained the Slovak position to other EU finance ministers on Sunday.
The EU must create clear rules on debt restructuring and private sector participation in bailouts to prevent more contagion from the euro zone debt crisis, Miklos said earlier on Wednesday.
The plan, together with a push by top euro zone economy Germany for the private sector to share the risks of future sovereign debt crises, has spooked investors and exacerbated a sell-off of bonds from Ireland and other debt-laden countries in the region.
"It is necessary to make clear rules about the participation of the banking and financial sectors and debt restructuring to prevent contagion," Miklos told reporters in Bratislava.
The selloff of peripheral euro zone bonds continued on Wednesday, with yield spreads widening on Spanish and Portuguese debt and the prices of insurance against sovereign debt default rising to record highs. [
]A German government paper seen by Reuters that Merkel's government wants to put forward as a framework for discussions at the EU level said private investors should face "haircuts", or writedowns, in case of bailouts.
The new crisis mechanism would come into force in mid-2013, after the current safety net expires.
