Greece's parliament has approved a batch of minor reforms demanded by bailout creditors, but the government is still struggling to finalize tougher decisions required to receive a new rescue loan installment.

The bill covering technical issues from tax and energy to pensions was adopted with backing from the left-led governing coalition early Friday.

However, the government has failed to reach an agreement with its European creditors on the thornier issues of which mortgage-holders to protect from primary residence foreclosures, and whether to hike tax on private education.

The government and its creditors have said they want a deal by Monday, which would allow finance ministers from the countries that use the euro to grant Greece a 2 billion euro loan installment.
