Main opposition New Democracy leader Antonis Samaras on Sunday urged the Greek people to stay calm and united, in a statement after Prime Minister Alexis Tsipras announced that capital controls would likely be imposed. At the same time, he called on Tsipras to cancel plans for a referendum, which he said now “lacked content” and had become a parody. Alexis Tsipras knows that it was primarily his own mistakes that forced him to even close the banks, Samaras said. The country must remain in the heart of Europe and the euro, Samaras emphasised, and the prime minister has an obligation to continue the negotiations. If he cannot do it himself, let him brave a great national understanding, he added. “On our part, we will do everything to restore normality in the country and return hope to the Greeks,” the ND leader said.
