Former SYRIZA leader Alekos Alavanos has announced plans to launch a movement that will campaign for Greece to leave the euro.
"All countries have a Plan B for Greece, only Greece does not have a Plan B should it have to leave the euro," Alavanos told Skai television on Tuesday.
He said the movement would aim to stand in the European Parliament elections in 2014 and would favor a return to the drachma.
"If Greece were to exit the European Union we would be much better off than we are today and would never have had to reach this point," he said, adding "that no country has ever managed to exit a crisis with a 'hard' currency. The euro is a hard and expensive currency."
He said that his movement will also favor the nationalization of banks and for Greece to repudiate its debt.
"It is madness to have the same currency as Germany when Germany, unlike us, has a stable economy," Alavanos said.
