A break-up of the euro zone is necessary for Europe's future, the Czech Republic's former president told CNBC on Thursday, adding to the increasing calls for a dissolution of the single currency area.
"I fully agree with the political stance of [anti-euro] parties in Europe. I think this is necessary for Europe," Vaclav Klaus, the president of the Czech Republic until six weeks ago, told CNBC at the Russia Forum in Moscow on Thursday.

"The change must come from below and it must be done in a normal political discourse, in a normal political interplay of parties in Europe," he added.
The rise of anti-euro parties has been seen across Europe, with Beppe Grillo's "Five Star Movement" in Italy, SYRIZA in Greece and the U.K.'s UKIP party all increasing their share of votes. The latest party to promote an anti-euro agenda is the "Alternative fuer Deutschland" movement, launched in Germany on Sunday.
In his conversation with CNBC, Klaus rejected being termed a "euro-skeptic", saying he was a "euro realist" who opposed people who are "naïve" about Europe.
"There is no way to accelerate economic growth without solving the political issues in Europe," Klaus said. "European politicians must stop their indecision and they must do something, but it does not mean centralizing more. On the contrary, they must do the opposite and increase the role of individual member states."
Klaus said Cyprus's contentious ten billion euro ($13 billion) bailout in March, was "just another example of how dysfunctional the euro zone is."

"Europe simply made a tragic mistake introducing one single currency to such a heterogeneous group of 17 countries. There is now no way out of it," he said.
"I wouldn't blame Greece and I wouldn't blame Cyprus, they are victims of the euro zone system and they made just one mistake by entering the euro zone system."
