Over the past year, Kaja Kallas has developed an image as a strong supporter of Ukraine in its war against Russia. The next battlefield for the Estonian leader is closer to home … same-sex marriage. Currently non-existent throughout the former Soviet nations, same-sex marriage has emerged as one of the major issues in coalition talks led by Kallas, the Estonian prime minister whose party won the most votes in elections in early March. For the liberals, this could be their best chance to get gay marriage on the statute books. While the registered partnership act of 2014 did grant some limited rights to gay and lesbian couples, it was never implemented as there was always a conservative party in government blocking its adoption.
