Biography
On October 2, 2017, Kaplin was elected party leader of the Socialist Party of Ukraine during a congress and he simultaneously stated his intention to take part of the 2019 presidential election. On January 27, 2018, during the "joint meeting of the political council and the central control commission of the Socialist Party of Ukraine" Illia Kyva was expelled from the ranks of the Socialist Party of Ukraine and deprived of the status of the head of this political force. Kyva claimed that his exclusion from the SPU was illegitimate. Meanwhile, according to the legal registration of the Socialist Party Kyva was the legal chairman of this party. Kyva was nominated by the Socialist Party on November 3, 2018, for President of Ukraine in the 2019 election.

According to a 2018 survey (of all Ukrainian politicians) by the "Committee of Voters of Ukraine" most of Kaplin's election promises cannot be fulfilled even theoretically.

In the 2019 Ukrainian parliamentary election Kaplin lost reelection as an independent candidate in single-seat constituency 144 (Poltava Oblast).
