The climate in the markets changed after Bloomberg news agency published a poll showing SYRIZA having a 6.5 percentage point lead over ND and analyzed the main opposition's policy, ND parliamentary spokesman Adonis Georgiadis told Skai TV on Thursday.
"Unfortunately, markets from now on do not only listen to Samaras, but to Tsipras as well. When they hear all these insanities about changing everything when they come to power, how are markets supposed to react?" Georgiadis wondered.
SYRIZA deputy Giorgos Stathakis, in statements to the same TV station, said that "the government rushed to draft its own roadmap of exiting the IMF. But, the other side does not embrace it."
