Speculation is again rife that Greece may soon leave the eurozone.

Greece's parliament is voting on painful budget cuts and labour market reforms that must be passed in order for Greece to receive its latest round of bailout money. Prime Minister Antonis Samaras has warned that if the vote fails, the government will run out of money by 15 November and be forced out of the single currency. Even if the vote passes, the government still needs to implement the reforms - something the previous Greek government noticeably failed to do. Tax rates were raised, but the taxes were not collected. Promised privatisations were not carried out. Civil servants were suspended but not dismissed.
