CRISIS IN THE MAKING

Despite Greece's sudden return to the spotlight, trouble had been brewing for Samaras's government since May.

The momentum ought to have been clearly in his favour: Greece had just returned to bond markets after a four-year exile, it had reported a primary budget surplus after decades and there were signs of an economic recovery.

But Greeks were hurting from four years of wage and pension cuts. Unemployment was over 25 percent. The economic malaise helped Syriza storm to victory in European elections in May.

A botched introduction of a new property tax over the summer further added pressure on the government. By early autumn, polls showed Syriza firmly ahead and the troika was demanding further pension reform and tax hikes to ensure a near balanced budget.

Samaras was convinced he would not get any more austerity measures passed in parliament, a government official said.

Hoping to wrest back the momentum, he announced in late September a surprise plan to exit the unpopular bailout programme a year ahead of schedule.

But talks with creditors didn't follow as he hoped. In mid-November, the two sides were growing further apart on the 2015 budget. The IMF and EU said Athens needed to find cost-cutting and revenue-raising measures for an extra 2.5 billion euros.

Greek government officials argued that they only needed to find additional cuts worth about 500 million euros.

They were infuriated by the lenders' request for a contingency reserve for emergency outlays to be beefed up to 1.2 billion euros from 1 billion euros the previous year, arguing that it flew in the face of an economic rule.

"This rule implies that in 2015, a year of high growth and declining risk, the contingency reserve ought to decline. Yet you assume the contingency reserve ought to rise by 200 million euros!" Finance Minister Gikas Hardouvelis wrote in a Nov. 29 document obtained by Reuters that Athens sent inspectors.

The lenders' stance suggested they wanted the extra money in case political uncertainty and elections further delayed reforms, knocking targets even further off track, Greek officials said.

"The (bailout) talks crossed paths with the presidential vote...leading us to a very tough situation," said Deputy Prime Minister Evangelos Venizelos. "We did the best we could."
