After the optimism that followed news of an agreement between Greece and its international creditors yesterday (Monday), the bailout deal looks set to hit another speed bump.

Greek Prime Minister Alexis Tsipras is understood to be facing a tough battle to win support for the terms of the bailout from his coalition partners.

Defence Minister Panos Kammenos has already said he will not support the four pieces of legislation that need to be passed by Wednesday in order for the deal to progress.

The reforms on pensions, the VAT system, tax revenues and the labour market need to be passed, otherwise the new €82-86 billion bailout will not be released. Greek banks will collapse and the country will be forced to leave the eurozone.

When Mr Tsipras returned to Greece on Monday after 17-hours of talks through the night, anti-austerity protesters and civil servants called for a 24-hour strike on Wednesday.

Tsipras and his Syriza party was elected in January, largely on the basis that he would end austerity in the country. But the economic reforms are austerity measures, designed to show creditors that the country will cut costs in order to pay back its bailout.
