(ANSA-AFP) - TALLINN, JUN 4 - Estonian Prime Minister Kaja Kallas on Friday called for talks on a new government after her ruling coalition fell apart, urging unity because of security concerns over neighbouring Russia. Kallas spoke to reporters after President Alar Karis accepted her request for ministers from the Centre party, including Foreign Minister Eva-Maria Liimets, to be removed from the government. The dismissal of the Centre party follows weeks of political deadlock, including a vote on an education bill in which the coalition partner voted against the government and with the far-right EKRE opposition instead. "It's honest to say that this agreement is over and we're going to form a new coalition," Kallas said. Kallas's Reform party has proposed to begin coalition talks with the right-wing Isamaa conservatives and the Social Democrats. The Centre and Reform parties have alternated in government over the nearly three decades since Estonia broke free from the crumbling Soviet Union. (ANSA-AFP).
