Stock markets and the euro fell sharply Friday after Greece's crucial bailout was put on hold by its partners in the 17-nation eurozone and the leader of a small partner in the country's coalition government said he would vote against the demanded austerity measures.

Just a day earlier, the feeling surrounding Greece was very different. Following weeks of discussions, the Greek government appeared to have done enough to pacify creditors.

Greek Prime Minister Lucas Papademos and heads of the three parties backing his government _ including George Karatzaferis ho Friday railed against the deal _ agreed to deep private sector wage cuts, civil service layoffs, and significant reductions in health, social security and military spending.

Investors breathed a sigh of relief that the agreement would allow Greece to get a euro130 billion ($173 billion) bailout package and avoid a bankruptcy next month that could send shockwaves around the financial markets.

But finance ministers from the other 16 eurozone states threw up a roadblock late Thursday and insisted that Greece had to save an extra euro325 million ($430 million), pass the cuts through a restive parliament and guarantee in writing that they will be implemented even after planned elections in April. News that the leader of a small partner in Greece's coalition government would now vote against the austerity measures deepened the gloom on Friday.

The renewed fears of a Greek default, which could send shockwaves around the global economy, dented sentiment in the markets Friday.

In Europe, the benchmark index in Athens 3.7 percent down by late afternoon local time. The FTSE 100 index of leading British shares was down 0.9 percent at 5,840 while Germany's DAX slid 2 percent to 6,653. The CAC-40 in France was 1.5 percent lower at 3,373.

The euro was also hit hard, trading 0.8 percent lower at $1.3162.

Wall Street was poised for a sharply lower opening, too _ Dow futures were down 0.7 percent at 12,750 while the broader Standard & Poor's 500 futures fell 0.9 percent to 1,336.

The prevailing view remains that a deal will be cobbled together but the uncertainty is weighing on stocks. Once all the demands have been fulfilled, the eurozone will give Greece the green light to start implementing a separate bond swap deal with banks and other private investors designed to slice some euro100 billion ($132 billion) off Greece's debt load.

"For all the rhetoric it is probable that a deal will still be reached because the consequences of not doing so would be so damaging for the EU as a whole," said Gary Jenkins, managing director at Swordfish Research.

However, it is possible that the Greek politicians "suffer from negotiating fatigue and decide that putting their people through the austerity measures are not worth it."
