Self-confessed Eurosceptic Michael Portillo visits debt-stricken Greece. He believes that the euro crisis must have shaken the Greeks' faith in Europe's single currency and wonders if there'll be a desire to revert to the free-floating drachma. In Athens he meets everyone from a destitute young family to the former finance minister and the outgoing Prime Minister, and is surprised by some of their answers.

Meanwhile in Germany, Europe's economic powerhouse, Michael encounters the taxpayers who are paying most towards Greece's mammoth financial bailout while having to watch angry Athenians burning the German flag.

With tensions rising in the Eurozone, is this the moment it becomes more united, or will it be pulled apart?
