Barroso to visit Greece today

Tensions are running high in Greece ahead of today's visit by European Commission President Jose Manuel Barroso to Athens, amid increased speculation the country is heading towards debt default.

Over the past few days, numerous high-ranking officials have publicly talked about Greece's possible default and exit from the Eurozone, without being contradicted.

Some analysts see these comments as a way of putting more pressure on Greece and not as an immediate threat of the country exiting the Eurozone.

European governments have already twice asked their parliaments to approve emergency loans to Greece.
