BUDAPEST/WARSAW (Reuters) - The prime ministers of Poland and Hungary accused European Union countries of blackmail on Wednesday, digging their heels in after vetoing the bloc’s budget and post-COVID recovery package.The two countries on Monday blocked the EU’s 2021-2027 budget and the recovery plan, worth a combined 1.85 trillion euros ($2.2 trillion), because access to the funds would be conditional upon respecting the rule of law. Polish Prime Minister Mateusz Morawiecki said that he would ask lawmakers to vote on a resolution supporting the government’s stance regarding the veto, after an address to parliament in which he railed against what he said was unequal treatment of some member states. “If our partners do not understand that we do not agree to unequal treatment of states ... then we will really use that veto in the end,” he said. “The EU must be built on a foundation of law and legal certainty .... Without this principle of legal certainty, the EU is a mechanism of arbitrary decision-making by Eurocrats and de facto by the European oligarchy,” he added. He said one reason that some EU states wanted to pressure and “blackmail” Poland was the country’s opposition to tax havens. “We will not let ourselves be blackmailed,” he said Poland has made reforms of the judiciary a key plank of its bid to reshape Poland and remove what it sees as a residue of Communist influence. Critics, including the European Commission, say the reforms are designed to increase political control of the courts.
