* Hungary post-election rally fizzles after cbank attack
(Updates prices after Greece, Portugal downgrades)

WARSAW/PRAGUE, April 27 (Reuters) - Hungary's forint showed its biggest daily drop this year on Tuesday, falling more than 2 percent to lead emerging Europe down as a post-election rally fizzled and concerns rose over Greece's aid package.
Markets in debt-laden Greece took another battering on Tuesday on the possibility Athens might not secure aid in time to meet a debt deadline on May 19. [
]The prospect stoked fears that other euro zone states might face similar problems, hitting appetite for riskier assets that weighed on emerging European Union countries despite their better debt position. There was an abrupt reversal of a Hungarian market rally that had followed a decisive election victory for the centre-right Fidesz, which in Sunday's run-off vote won the two-thirds majority needed for vital reforms. [
]Central bank Governor Andras Simor said on Monday intervention on the forint could not be ruled out, adding pressure on the forint.
Investor nerves were also tested by comments from Fidesz officials calling on Simor to resign; the party has stepped up criticism of Simor's past investments in a Cyprus-based firm and over what it said were serious policy mistakes. [
]"We all knew what Fidesz would do once they take power," a Budapest dealer said, adding that the attacks on Simor had a minor market effect compared to Greece.
The forint <EURHUF=> fell to bid at 268.88 to the euro by 1558 GMT, hitting a nearly two-month low on stop losses. Hungarian bonds were more subdued; yields rose 8 basis points, a fraction of the drop to multi-year lows this month.
Hungarian assets rallied following a decisive victory in the first round of elections on April 11 that first gave Fidesz a strong mandate for deep economic reforms in the country of 10 million that has relied on IMF aid.
But tension between the new ruling party and the central bank, and a 25 basis point rate cut on Monday that was followed by comments from Simor not ruling out interventions on the FX market have made the bounce short-lived. [

GREECE STORY
The forint drop hit peers in the region, with the Polish zloty <EURPLN=> losing 1.4 percent to the weak side of 3.93 per euro. The Czech crown <EURCZK=> and Romania's leu <EURRON=> fell 0.5-0.6 percent against the common currency.
Stock markets fell more than 1 percent, except for Budapest <
> which held up better with a 0.2 percent drop after cutting losses late in the day.Analysts say persistent uncertainty over Greece could affect emerging Europe, especially if the euro drops more. Central European currencies extended losses late Tuesday afternoon after ratings downgrades for Greece and Portugal. [
]"If the EUR/USD breaches 1.3268, nothing in the world will stop it from going all the way to 1.30... No way we won't feel that," another Budapest dealer said. "We're not insulated from the euro zone like some people like to believe. We are emerging markets... but this is Europe."
So far, however, the region's better growth outlook and lower debt levels compared to euro zone periphery states have continued to attract investors fleeing the euro, and pushed currencies, bonds and stocks to multi-month highs this year.
Greek 5-year credit default swaps (CDS) hit a record high earlier on Tuesday, touching 798 basis points, while the Czech 5-year CDS stood at 77 bps, and Poland's at 105 basis points.
