Lenin was not the leader of the "Soviet party." There was no such thing as a "Soviet party." A "soviet" is not a political party at all. The word "soviet" means "council" and referred to the groups that arose in many Russian cities and towns comprised of representatives, or deputies, of workers, peasants and soldiers. Most of these soviets had the support of the people in their cities and towns and had virtual governmental authority in many of them. The members of the soviets would be members of the various political parties, such as the Bolsheviks, Mensheviks, Socialist-Revolutionaries, Kadets and others. Lenin was head of the Bolshevik Party and "soviet" is not just another word for Bolshevik or Communist.
Vladimir Lenin was the leader of the Bolsheviks during the "soviet revolution", although technically it is not called the soviet revolution, but the Russian Revolution or Bolshevik Revolution. The Soviet Union had not come into being until 1922.

There are three possible answers to this question because there were (at least) three political parties that could be deemed "socialist revolutionaries. First is the Bolshevik Party. Vladimir Lenin was the chief leader. Second is the Menshevik faction of the Russian Social Democratic Labor Party. Julius Martov was the chief leader of that party. Third is the Party of the Socialist Revolutionaries. Victor Chernov was the chief leader of that party. Most likely this question refers to the Bolshevik Party under Vladimir Lenin, since it is the political party which overthrew the Russian Provisional Government (not the Tsar) in the October Revolution and later became the Communist Party.
