Greek politicians have failed to form a government and will now head towards holding a new election.

Polls show the vote could favour the country's leftists who want to renege on the terms of bailout agreed on by the government earlier in the year.

This will see the country push closer towards an exit from the eurozone, a situation which IMF chief Christine Lagarde says could get "quite messy".
