Athens postponed late Monday sending a list of proposed reforms aimed at obtaining a four-month extension of its bailout lifeline until Tuesday morning, a Greek government source said.
"The list of reforms will be sent tomorrow (Tuesday) morning to the finance ministers of the Eurogroup," the source said hours before a midnight (2300 GMT) deadline agreed on Friday to send the proposals expires.
The source added that the measures would include all the promises made by Prime Minister Alexis Tsipras's hard-left Syriza party before its sweeping election victory in January.
These include free electricity for 300,000 poor families, free access to health care, food and public transport coupons and aid for those on low pensions. The source did not say how much extra these measures will cost.
Other measures include a more "just" taxation system, measures to tackle tax evasion and corruption and to crack down on smuggling, as well as streamlining the civil service to reduce bureaucracy.
The finance ministers of the 19-nation eurozone need to approve the measures before they agree to extend the terms of Greece's 240-billion-euro ($270-billion) bailout programme, which otherwise will expire on Saturday.
The source said that the finance ministers would hold a conference call on Tuesday to this end.
