A new political party has been launched in Greece which supports leaving the euro and returning to the drachma.
Plan B leader Alekos Alavanos said in Athens that Greece could not emerge from recession as long as it was locked into a common currency.
Mr Alavanos, a former leader of Syriza, an opposition party, argues that leaving the euro would be a "little shock" but, through devaluing the drachma, it would soon yield positive results and set an example to other eurozone countries.
So far the new party is tiny, with only about 400 members.
The BBC reports the prospect of Greece's departure from the euro has hung over the country since its financial crisis erupted in 2009.
Opinion polls suggest most Greeks favour retaining the euro.
The government insists there is no turning back and insists talk of Greece leaving the euro is now a thing of the past.
