UPDATE 2-Greek PM's allies seek more time for austerity cuts-sources

* Socialists, moderate leftists want two more years for cuts

* Political leaders agree to meet again

* Greece must produce cuts to satisfy EU, IMF lenders

ATHENS, July 30 (Reuters) - Greek Prime Minister Antonis

Samaras's allies are pushing for two more years to implement

unpopular austerity cuts before they sign off on them, sources

close to the parties said on Monday, potentially delaying a deal

on the savings demanded by lenders.

The three parties in Samaras's coalition have agreed on the

bulk of the nearly 12 billion euros ($14.7 billion) in cuts that

Greece must produce to satisfy inspectors from the European

Union and International Monetary Fund bailing out the nation.

But his two leftist partners insisted during an inconclusive

meeting on Monday that Greece needed more time to implement them

in the wake of a deeper than expected recession.

"There is agreement on the strategic plan. Discussions will

continue, there will be another meeting in the next few days,"

Democratic Left leader Fotis Kouvelis told reporters after the

two-hour-long talks.

Hours before the three leaders resumed talks to nail down

the final 1.5 billion euros in cuts, the socialists and moderate

leftists backing Samaras banded together to demand the cuts be

spread out over four years instead of two, party sources said.

Greece's bailout insists on the cuts in 2013 and 2014.

"The two leaders have agreed to ask for an extension of the

programme because all these harsh measures cannot be implemented

in two years' time," a party official said after talks between

Kouvelis and Socialist chief Evangelos Venizelos earlier on

Monday.

A second party official said the Socialists - facing the

brunt of voter anger over their support for austerity - wanted

6.7 billion worth of cuts pushed through in 2013 and 2014, with

the remaining cuts saved for the following two years.

That plan, however, was expected to meet resistance from

Samaras, who wants to restore Greece's rapidly sinking

credibility with lenders as a first step before trying to

renegotiate the terms of the deal.

"We are trying to find the perfect mix," Finance Minister

Yannis Stournaras told reporters after the meeting. "We all

agree that two more years are needed, that the road is uphill

and difficult."

MORE TIME

All three parties in Samaras's government agree that Greece

requires additional time to meet its debt targets because of a

deeper-than-expected slump that has been likened to a Greek

version of America's "Great Depression".

But Venizelos, the once-powerful finance minister who

negotiated the reviled bailout, is particularly keen to distance

himself from the latest round of cuts as his party tries to

rebuild after being pummeled in elections this year.

The once-dominant Socialists were beaten to a lowly third

place in the June vote behind the radical leftist Syriza group.

Kouvelis' Democratic Left party, which campaigned against

the 130-billion-euro rescue before allying with the victorious

conservatives, is also under pressure to show voters it will not

sign up to new austerity cuts without a fight.

The bickering among Greek political leaders comes against a

backdrop of increasing impatience from the country's European

partners and the IMF, who must once again decide whether to

continue funding the country or cut it loose from the euro zone.

Mired in its fifth year of recession and wholly reliant on

bailout funds, Greece is set to run out of money within weeks if

a new tranche of aid is withheld - leaving it at risk of

crashing out of the single currency.

Even if the political leaders were to seal agreement on the

cuts required under its bailout, a growing sense of gloom has

set in on the country's future in the euro.

Speculation has grown that Greece might need a second debt

restructuring to bring its debt back on a sustainable footing

and that its 130-billion-euro bailout may need to be hiked by a

further 20-50 billion euros - at a time when there is no

appetite to give Greece more time or money.

Policymakers are working on "last chance" options to bring

Greece's debts down and keep it in the euro zone, with the ECB

and national central banks looking at also taking significant

hits on the value of their bond holdings, officials have said.
