Greece won't pay back IMF loan tonight

Greece's Finance Minister says the country will not pay back the IMF loan which is due tonight.

But Greece is understood to be considering fresh proposals from Europe in a last-ditch effort to find a deal.

The mood in Athens is tense, as citizens prepare to vote in a referendum on the matter, which is seen as a vote on membership of the Eurogroup.
