In the minister's words, by banning the organization on the eve of presidential elections, Moscow demonstrated it did not want an impartial assessment of the vote.
"We can only regret the move. It is an organization that did election studies across the region – not just in Russia but also in Georgia, Moldova and elsewhere," Linkevičius told BNS on Tuesday evening.
"The list of foreign agents has been enlarged on the eve of the Russian elections. All we can do is assume that the state does not want an international impartial assessment and analysis," the minister added.
He spoke after Russia's Justice Ministry on Tuesday blacklisted the International Elections Study Center (IESC) and Germany's European Platform for Democratic Elections (EPDE). The decision was taken in accordance to a March 12 resolution from deputy prosecutor general, the ministry said in a statement on its website.
