Will Greece rebuild their economy in or out of the euro?

This weekend the people of Greece will once again be asked to make a far-reaching decision about their country's financial future.

Should they vote for a mainstream party committed to the unpopular austerity measures imposed by the IMF and EU.

Or should they pick one of the extreme parties pledged to changing the terms of the tough austerity drive - a move which could bring on an exit from the euro currency.
