Greece has sent its creditors a long-awaited list of reforms with a pledge to produce a small budget surplus this year in the hope that it will unlock badly needed cash.

The European Union and IMF lenders, informally called the Brussels Group, will start discussing the list today, a euro zone official said, although a Greek official said the examination would begin on Saturday. 

Their approval, followed by the blessing of euro zone finance ministers, will be needed for Athens to unfreeze further aid and stave off bankruptcy.

Athens has not indicated whether the latest list will contain a more far-reaching reform programme than a previous list of seven reforms on broad issues ranging from tax evasion to public sector reforms, which failed to impress lenders.

The new list includes measures to boost state revenues by €3bn this year, but will not include any "recessionary measures" like wage or pension cuts, a government official said.

The list estimates a primary budget surplus of 1.5% for 2015 - below the 3% target included in the country's existing EU/IMF bailout - and growth of 1.4%, the official said.

Prime Minister Alexis Tsipras's left-wing government has previously said the list will include measures to improve investor sentiment, boost tax revenues, and judicial reform.

The government is also expected to address some form of pension reform, though it has already excluded any attempt to raise the retirement age or other sensitive measures that would be viewed as cutting pension payouts for austerity-hit Greeks.

It is also expected to include labour reform aimed at fighting the increase in unregistered workers, and also include commitments to allow privatisations to proceed.

The government has rowed back on pledges made in its early days to roll back asset sales, but it still wants to retain management control after selling off stakes.

Athens needs to show its creditors it is committed to structural reforms and that the measures will not derail its budget. 

Though Athens remains at risk of bankruptcy without fresh aid, publicly the mood in talks between Greece and its lenders has improved in recent days after weeks of acrimony that had raised the risk of a Greek euro zone exit.

France's Finance Minister Michel Sapin earlier urged Greece to present detailed reform proposals to allow for a deal with its euro zone peers.

The reforms list submission came as Greece's government denied a report in Germany's Bild newspaper that its outspoken finance minister Yanis Varoufakis was considering resigning.

A prominent figure in the Greek government who has won fans and angered interlocutors with sharp-tongued attacks against austerity, Varoufakis has kept a markedly lower profile in recent days with fewer interviews and public appearances.

But he took to Twitter to deny the reports, saying: "Every time the negotiations heat up, some new rumour of my resignation, demise etc. springs up. Somewhat amusing..."

Bundesbank opposes more Greek emergency funding

Earlier Bundesbank chief Jens Weidmann said he was opposed to giving Greece more emergency loans, accusing the new government in Athens with frittering away a lot of trust.  

"Until the autumn, an improvement in the economy had been discernible. But the new government has gambled away a lot of trust," Weidmann said in an interview with the weekly Focus magazine. 

"I am opposed to an increase in the emergency loans," said Weidmann, who as head of the German central bank sits on the European Central Bank's decision-making governing council.
