Athens, Greece (BBN)-Greek Prime Minister Alexis Tsipras is facing a tough battle to win support from coalition partners for the third bailout offered by eurozone leaders.
Four pieces of legislation must be passed by the end of Wednesday including pension and VAT reforms, reports BBC.
But Defence Minister Panos Kammenos, a junior coalition partner, has already said he will not support the measures.
If the deal fails, Greece's banks face collapse and the country could then be forced to leave the euro.
The bailout is conditional on Greece passing all the agreed reforms - including raising tax revenue and liberalising the labour market - in parliament by Wednesday.
Finance ministers from all 28 EU countries are holding a scheduled meeting in Brussels on Tuesday morning, where they will discuss the situation in Greece.
BAILOUT DEAL AT A GLANCE
Following about 17 hours of summit talks in Brussels an EU statement on Monday spoke of up to €86bn (£61bn) of financing for Greece over three years.
Although it included an offer to reschedule Greek debt repayments "if necessary", there was no provision for the reduction in Greek debt - or so-called "haircut" - that the Greek government had sought.
Parliaments in several eurozone states also have to approve any new bailout.
CABINET RESHUFFLE EXPECTED
As Tsipras returned to Greece on Monday, anti-austerity demonstrations took place and civil servants called for a 24-hour strike on Wednesday.
Many Greeks and others believing unduly harsh terms are being imposed have expressed their widespread anger online using the hashtag #ThisIsACoup.
Defence Minister Panos Kammenos, whose Independent Greeks party underpins Tspiras's coalition government, likened the situation to a "coup".
He said he would not support the agreement - although he wants to remain in government.
The BBC's Mark Lowen in Athens understands the prime minister is expected to reshuffle his cabinet and possibly form a new unity government later this week.
Tsipras came to power after his left-wing Syriza party won elections in January on a promise to end austerity. Greece has already received two bailouts totalling €240bn since 2010.
Greek banks have been closed for two weeks, with withdrawals at cash machines limited to €60 per day, and will remain closed until after Wednesday.
'NO GREXIT'
Before the latest deal offer there were fears Greece would be forced to leave the euro.
On 30 June, Greece missed the deadline for a €1.5bn (£1.1bn) payment to the International Monetary Fund (IMF), becoming the first European Union country to do so.
It missed a second debt payment to the IMF on Monday.
But following the talks, European Commission chief Jean-Claude Juncker, said: "There will not be a 'Grexit'."
Tsipras said that after a "tough battle", Greece had secured debt restructuring and a "growth package".
He also said he had the "belief and the hope that... the possibility of 'Grexit' is in the past".
Jeroen Dijsselbloem, the head of the eurozone group of finance ministers, said the agreement included a €50bn Greece-based fund that will privatise or manage Greek assets. Out of that €50bn, €25bn would be used to recapitalise Greek banks, he said.
Eurozone finance ministers meeting in Brussels discussed providing "bridge financing" that would cover Greece's short-term needs.
But final decisions depend on Greece "rebuilding trust" by legislating the first set of measures.
