The Greek parliament has begun an emergency debate on a second round of conditions demanded by international creditors for a new bailout - a vote that could threaten the coalition government.
MPs will later today vote on judicial and banking reforms set as a requirement by other eurozone countries for a third Greek rescue package worth €85 billion.
Prime Minister Alexis Tsipras is already relying on support from pro-European opposition parties to gain parliamentary approval for bailout conditions, amid growing dissent within his left-wing Syriza party.
Mr Tsipras has imposed a tough new round of austerity measures this month and needs to conclude the bailout negotiations before August 20, when Greece must repay loans worth more than €3 billion to the European Central Bank.
